Grizzy RV in West Yellowstone

Thanks for all advise and opinions, I appreciate hearing first hand what we can expect. After looking at all our options we will be booking at GrizzlyRV, In fact I may not even tow our car and just rent a passenger van when we get there (I will call ahead and reserve one!) This way all of our party will be able to tour the park together. We are traveling with another MH and a 40' 5er. So we will be reserving 3 sites at Grizzly next to each other. I spoke with Grizzly and they assured me that we will have our sites next to each other. We are very much looking forward to our Yellowstone adventure!
