My BF and I will travel to Grand Tetons and Yellowstone NP in August. Neither of us have ever been and we need some help with possible hotels and must sees at each place in case we never get back there again. So far we plan to fly into Idaho Falls and rent a car there. We will drive to GTNP and spend 3 days. We thought we should stay somewhere in Jackson Hole or is there a more budget friendly place near the park to stay?Our main objective in GTNP is to take some great photos and do some hiking and/or 1/2 day rafting trip. We would like probably a half day hike, nothing too advanced. We will then drive to Yellowstone. Is Gardnier the best place to stay there? We definetly want to see Old Faithful but also the park's "Grand Canyon". We thought we would then fly out of Yellowstone Regional airport. Will it be possible to leave the rental car at that airport? Thanks for any help or suggestions you have.
