Booked 6 months in advance and based it on many good reviews. Was promised a new, upgraded campground with a premium site. Found new section is not completed and under construction. Was placed on site 40, which is terribly unlevel, a muddy mess with no crush, no patio and a tree that lays disgusting bushy bug-like buds every day all over everything. The only site like this. We could not enjoy it outside at all. No dog park as advertised. Paid a good deal for a week and was very disappointed. It was far from all the attractions at Yellowstone. It takes 30 min to get to the west gate, and over an hour and half to any points in the park. People seemed nice enough. Did see a moose close by and the laundry room and store were nice. The store was way overpriced tho. West Yellowstone seemed much nicer and closer to NP. Wouldn't stay here again. So disappointed that we booked a week here. The site was horrible and I was told it was a nice site when I questioned it by staff.
