Seriously,
For those looking for hotel rooms, yeah, it's expensive and a PITA. The hotel rooms I can sort of live with, it's the CHP harrassment that I cannot live with. Still....
Everytime I did get a hotel room, there were a number of us. One to two per bed, and 5-7 'enchilada'd' on the floor. It was the only way to make it affordable.
Forget RV's, last I saw RV's would be close or over $1,000 for 4 days *and* you gotta grab your ankles to pay for gas. Ask me how I know.
The best thing you can do, is get a bunch of people together for one double bed room. (and for the love of god don't TELL the hotel that you got 7-9 people in one room like my idiot buddy who slipped and almost cost us a hotel 3 years ago!)
Keep looking around for deals. Don't forget to look on Craigslist, you never know if someone will open up a guest bedroom.
