My cheapest would be when my extended family (my parents, 2 sisters & their kids and my family -- 12 of us all told) rented a 5 bedroom house with a pool for a week just off of 192. Beautiful home with lots of space. Beat the heck out of 4 hotel rooms for 7 nights. We brought pre-prepared meals (huge ham, big pot of spaghetti, etc.) that we could snack on during the week after we got back from the parks without cooking. We ate breakfast before we left every morning so that the only meal we had to eat at the parks was lunch. (Not saying that we ate every night at the house). It was so easy and relaxing. I already had my annual pass so it only costs my family $280 for the room (for the week) plus any meals we ate in the park.
