The wedding venue is very EAST of Phoenix. If you're looking to stay closer to the venue, Gilbert and Mesa have amazing restaurants + activities. Both towns are about 20mins from the PHX airport.
If you'd prefer to stay closer to downtown or in scottsdale (north of Mesa/Gilbert) you're of course welcome to do so. It's still about 15-20 minutes from the airport but there are also lots of activities in these areas.
See the "Things to Do" tab that has activities in all 4 of these areas.
