Hi Gail,
A few things to be aware of: First, know that in Palm Springs you're actually *required* to have a contract that guests sign. So, do look into that. (More on this below.)
As for these specific guests: There a couple of common issues that come up around festival season in Palm Springs. Especially for the second weekend of Coachella, attendance skews pretty young. It's not unusual for inquiring groups to be under the minimum age for renting a vacation rental in Palm Springs. (Our ordinance requires the "responsible guest" signing the contract to be at least 25 years of age.) Every year, I find I have to turn a couple of such groups away.
It's a total pain, of course, but basically one has to explain to inquring guests in Palm Springs a couple of things:
1. That, whether or not they're comfortable with doing verification on Airbnb (and why would they not be?), you're going to have to get a copy of the responsible guest's government issued ID for compliance with our rules anyway.
2. That they are going to be met at or shortly after check-in to have rental rules explained to them and that all adult guests will have to sign the City's "Statement of Rules" as our regulations require.
3. That the responsible guest must meet the minimum age requirements.
4. The whole - "hey, Airbnb doesn't properly compute or display tax so we need to collect that via a reservation change or money request" thing.
5. In addition to any other important house rules you might have.
If you'd like more info on contract and guest meeting requirements, see the VRCD's "Education" page at http://www.palmspringsca.gov/government/departments/vacation-rentals/education-and-training
The videos are admittedly a little hokey, but it's actually pretty good information and very helpful to newbies! I'm a fellow PS vacation rental permit holder as well and you might also find my page on "Resources for Palm Springs Vacation Rental Owners" useful as well.
