In the past, I have created illustrations of the city/location for some property managers to leave out as a gift in the room. Another customer wanted a small map created with local highlights that should could include in her printed guest welcome letter that she gives to everyone who stays.
I really love working with hosts on creating these kind of things, because it definitely makes the stay more personal. Plus, it's a great way to get your guests to have a sense of what you love about the place they are.
In general, guests love the recommendations so I think the print plus a recommendations list is a successful piece. They can leave the recommendations behind and take the print with them if they want. (As a guest, I know that these extra touches do make the stay memorable; I now do have some of those postcards in frames around my house, as a memory of an amazing trip.)
It's also affordable. I love making illustrations, and send my clients the digital file when it's finished. Then, you just take the file to your local print shop and have them do the printing and trimming for you.
