We are looking at three tours that cover Yellowstone and Grand Tetons (Yellowstone and Grand Teton Nat'l Parks, Yellowstone and the Tetons: American Safari, and Paradise Valley, Yellowstone and the Tetons). If anyone has taken any of these recently (last 3 years?) please give us your opinions. Wondering about the sites you see, the level of activity, the hotels and food, ancillary activities, Tauck special events, etc. Any info helpful in helping us decide. thanks in advance for your thoughts!
