You can improve relationships by having your colonists entertain your guests.

To please a visiting faction provide quality guest beds, joy objects, and a pretty environment inside of their area. If they liked their stay, they might leave items for you. It also affects your relationship with that faction. If the relationship with a visiting faction is high, they will also bring more silver and more items.

Guest beds are made by converting regular beds with the "For guests" button.

Happy guests might also help you out with work inside of their area. If you want to prevent this, you can disable it entirely in the mod options, or make sure the work is not inside their allowed area.

Set up a guest area like animal areas. In the guest tab of visitors you can then select this area and make it the default for all guests.

The same way you can also specify where guests are allowed to buy things. Don't forget to use "Make Default" to apply your settings to all current and future visitors, or use the guests tab menu.

You can recruit guests either by forcing the recruitment, at a very high cost, or by making friends with them first to lower the cost. It always costs you relationship points with the guest's faction.

In order to recruit a guest at a reasonable cost, you have to increase their trust in your colonists. Hanging out with them will help, and having someone with a high social skill try and make friends with them is required as well. The amount of friends required is based on how many colonists you already have. Once a guest has enough friends, the "Force recruit" button on the guest's tab becomes "Recruit" and you can also recruit them from the guest overview tab.

Skilled recruiters recommend other colonists more effectively, and turn them into friends of the visitor over time. When a guest is recruited, it will cost some relationship points with his faction. The amount is displayed on the guest's tab.
If you force recruit, it costs additional relationship points but doesn't require the guest to have all friends. More friends will lower the cost, though, until you reach the lowest amount and it's not considered forced anymore.
Note that other guests can temporarily become upset (-5 mood) if you recruit from their faction. Also, guests will give their inventory to someone from their faction, when recruited.

Note that you will lose extra relationship points if no one from a group returns back home.

Royal guests work slightly different. The only friends that matter to them are your royal colonists. The amount is not important, only their (collective) rank. Each rank counts as one point. Recruiters understand this and will only make them friends with your royals. Royals can not be recruited by force.

When entertaining royals, higher ranks are more easily offended. This can be prevented by entertaining them with a royal colonist.

Note that most guests from an empire faction are protected from recruitment (see Interface below). They can only be recruited by force.

The final verdict of a group of guests directly affects the relationship with their faction.
The larger the group, the more it can change.

The relationship with the group's faction will always move towards the visiting score.
This means if the goodwill is already high, you need an even higher score to gain more.

Select a visitor and open the personal "Guest" tab. Here you can see how hard the person still is to convince and how much his faction will hate you if you succeed. You can also see your "Hospitality" rating, how you have affected your visitors as a group. All colonists set as "Negotiator" will do the recruitment. You can also choose to improve the relationship (make friends). The success of this will depend on your negotiator's social skills.

You can also see how many friends a guest needs to be recruited. This amount increases with the amount of colonists you already have.

This is also where you can force recruit someone or send his group away. Note that the entire group will leave. If you send them away after they have just arrived, they won't be upset.

If you can't see the "Guest" tab, it's either not a group of guests (caravans are not guests), or they are hostile, or you have a mod conflict that you should report in the discussions section.

There is also the guests overview tab at the bottom menu. Here you can see all present guests. The coloured bar to the left indicates who is from the same group.

If you see a "-" for recruiting, then that guest is protected from recruitment by his faction. They carry a "Death Acidifier" which destroys their equipment and hurts them, should you force them to join. These guests will not join you willingly (by making friends), unless they have a close relationship.

There is also a menu for configuring the defaults, like areas, etc. Here you can also close the current location for visitors.

If you experience guests with nothing to eat, there are different things you can do. You can offer food for sale, by placing food in the guests' shopping area. They will stock up on what they need, if they can afford it.
It's also a good idea to provide a free option for poor guests. You can allow guests to just take food for free (in the guests tab). They will take whatever food they like, if it is inside their allowed area. Only do this if you have plenty to spare. Alternatively, you can set up a nutrient dispenser and mark it as a vending machine for guests, but make it for free.
This is a cheap way to keep anyone from starving.
A word of note also goes for visiting royals: Royals only eat fine meals or better but rarely bring these themselves. So you'll have to be creative on how to keep them fed early in the game.
You might have to compensate their troubles with gifts to keep their relationship up.

The amount of silver that guests bring is based on the goodwill with your faction. If they don't trust you, they bring less silver. Older guests generally bring more silver.
It's a good idea to have some low quality beds available for free.

Groups of guests will randomly show up on their own, and more frequently if they enjoyed their stay. Using the Comms Console you can also invite them to come by at no cost.

If you are playing in a particularly cold region, consider using the FashionRIMsta mod, so your visitors can afford protection from the cold.

Sometimes people just gotta punch each other. If you're annoyed by taking the blame for when brawling guests knock each other out, use the mod Ugh You Got Me, which will prevent this from getting out of hand.

If you have custom faction mods, make sure to put this mod below them. Generally, the further down this mod is, the better.

Hospitality often does not go well with custom storytellers since many of them are not fully implemented.

This mod can be added at any time, without creating a new game. Removing it while visitors or guest beds are around can break your savegame.

You do need the HugsLib mod to use Hospitality. It has to be above Hospitality in the mod list.
