I am planning a 12-day vacation to Yellowstone and Grand Teton National Parks for Summer 2014 for 3 families. In total, there will be 5 adults, 2 teenagers, 2 older children, and 2 youngsters. The tentative plan is to stay 7 nights in Yellowstone Park and the rest somewhere in Jackson Hole or GTNP. We have reservations at Old Faithful Inn (which was a must for all of us). We are also wanting to make reservations somewhere else in the park. I have been reading up on Roosevelt Cabins and thought that would be the best option, but I have also been eyeing Yellowstone Lake Lodge and Canyon Lodge. Which one of those is the most convenient to the sites? How many days should we stay at OF Inn and how many at the alternate hotel/cabin? Thanks!
