Haha OK, i didn't realise to that - never mind, I found a way to make it all work that includes 2 nights in both Jackson and Gardiner (Yellowstone) :) There is a lot of small-town stops on this trip, so Idaho Falls, being a medium sized city, at least keeps my wife happy for somewhere to do a bit of shopping en-route! :)
