Flight
For any guests coming from out of state, the Palm Springs International Airport would be the closest airport to fly into. However, there are many airports within an hour or so, John Wayne, LAX, Ontario. Any of these should get you within an hour or so of the venue.
House Or Rental
The best bet if you are going to stay in the area will be to get a house on airbnb.com. There are tons of reasonably priced houses in the Pioneertown/Joshua tree area. Carly and Michael have stayed at airbnb's in the area and it has always been a great experience.
