Glacier/Grand Teton/Yellowstone NPs - what to do?

We're staying in the Tetons right now at Colter Bay and will be for another week. Our plans are to take a scenic float down the Snake River, do some hiking around Jackson, boat tour of Jackson Lake and possibly rent canoes and do some shore line exploring of our own.

Yellowstone is a multi day tour if you wish to see it all. You will spend one entire day on the west side of the park going from Moose Falls at the Souther entry to Mammoth Hot Springs at the northern end. Old Faithful will take around 4 hours to see incuding walking the miles of plank paths, visiting the Lodge and watching Old Faithful herself. The East side doesn't have as many features to look at but make sure to stop by and hike to Upper and Lower Falls.
