In the 1980"s my BIL wanted to skydive off El Capitan (Yosemite) so we piled our two kids and my IL and drove out in our van. All expenses were shared I had generous IL, DH and I did all the driving. We all stayed in the same room, kids slept on the floor, yes it was tight but we made it work. Anyone that you are close enough that you could live with for a week or two? We took a cooler with ice and drinks, fruit and snacks we built memories for a lifetime and had a ball. Hope it works out for you. Determination will get you halfway there!
