Over many years I've stayed at the Old Faithful Inn, Mammoth Hotel, Lake Lodge, Old Faithful Cabins, Lake Hotel and Grant Village. I'd recommend all except Grant Village, it's too much like a regular motel. I'd spend a day on each of the 'Grand Loop Roads.' From Bozeman, the northern loop would include an early morning trip up Lamar Valley to look for wildlife. a trip to the bottom of Tower Falls, perhaps a hike up Mt. Washburn, Canyon Visitor's Center, Artist's Point and Canyon Drive, Norris Geyser Basin and Ranger Museum at Norris Campgrounds, then back to Mammoth past the Obsidian Cliffs and a stop at Sheepeater Cliffs. Next day do the south loop, Hayden Valley (bison) Mud Volcano loop trail, Lake area, West Thumb Geyser Basin, Old Faithful, Paint Pots and other roadside attractions. Old Faithful Inn is my favorite place to stay, you can hear and feel Old Faithful erupt at night. Most hotels have formal dining rooms, many areas have cafeteria style dining also.
