My family has planned a trip to Yellowstone Nat'l Park over Memorial Day 2009. We are flying into SLC and driving part of the way the 1st day and will spend the night in Idaho Falls. We will then be spending one night at Mammoth Springs, two nights at Lake Hotel Cabins and one night at Old Faithful Inn. We are then planning on driving back to SLC to spend our final night before flying home.
We are debating if we should cancel one of our nights in YNP to visit Grand Tetons. Do you have any suggestions if we could just do this in a day from our YNP hotel or would it be best to stay the night in Jackson or Grand Tetons?
I am also concerned about weather in late May and know that it will be cold. Should most roads, hotels and restaurants in YNP be opened by Memorial Day? Just trying to be prepared with back up plans if necessary.
