You could easily spend your whole week in the park. We were there for 4 nights in May and didn't see it all.The park is as big as the state of Rhode Island. In summer,it gets full and you will have to negotiate the traffic and buffalo jams so it will take longer to get anywhere. We enjoyed the Inn at Old Faithful. It's the biggest log structure in the world. The lobby is beautiful. We ate dinner there. The food was good and the prices were reasonable. The Grand Canyon of the Yellowstone is beautiful. We also enjoyed Mammoth Hot Springs in the north end of the park.We saw a mother grizzly and 3 cubs on the road from Norris to Canyon.
