We are planning a trip in May 2011 from Pennyslvania to Yellowstone, the Grand Tetons and several parks in Utah.
Is it generally cheaper to (1) drive the whole trip, staying in motels, (2) drive and pull my own camper, camping along the way or (3) fly and rent a car or camper to drive and stay in motels or campgrounds?
How far in advance do reservations need to be made for stays near the national parks? Or can we just take our chances on finding lodging, whether we camp or stay in motels?
How much time should we allow for a trip like this, if driving the whole way vs fly/drive? We have 2-3 weeks available.
Thanks for a great site and hope to hear some good advice.
