Planning a first trip to Yellowstone/Grand Teton. Looking to spend 10 days to 2 weeks in the area. We have never been before and since we are driving from NJ, a low chance we will get that way again at least for a long time. Our total trip will be 3 1/2 to 4 weeks so the 10-14 days will be just for the Yellowstone area. We like to spend at least 3 nights at a time in a place. I would like to minimize driving at the parks. I can't decide if it is better to stay a week at one campground or stay 3-4 nights and travel around the parks. Interested in Grant Village for a few night and Colter RV park for a few so we can be closer to Grand Teton and have the luxury of hooking up. We can do dry/no hookups for 3 days. Maybe better to stay at the Fishing Bridge for a week if we can get in? Is it worth taking the time to go west of Yellowstone? I don't want to travel too much further west but if there is something really worth seeing, I don't want to miss it on this once in a lifetime trip. We are a middle aged couple with a 9 and 11 year old girls. We want to do some horseback riding and maybe a float ride down the river. Any suggestions for itinerary/ where to stay? Thanks!
