Mud Volcano, there was a ranger tour guide here and it was really informative. We got there just in time for the 1.5-2 hours tour, it was long but really worth it.
We missed some attractions, either because it was raining or we were short of time. I think 6 days to a week is the best time to spend if you plan to visit Yellowstone. Too much driving to do as the park is really huge. And that was not including hiking or walking on the many trails.

At Hatchet Resort (where we stayed), 30 minutes from South entrance. When we tried to reserve the rooms, the hotels inside Yellowstone were all fully booked. Heard that it need a year in advance booking if you plan to stay inside. Next time, we will stay at Jackson Hole since we still drove all over there for Chinese food! If you loved wilderness, stay here, it's a resort, so it basically have everything, nothing else in close proximity. Like the sale clerk said, it's as wilderness as you get. But if you love Chinese food or any other food other than the restaurant offers, and love to scroll along downtown, shopping and looking for some night life, stay in Jackson Hole.
