We spent the summer working in Moran WY and agree the two parks are way too large to enjoy staying in one place. Too much driving for a short period of time. A couple of our favorite activities was kayaking String and Leigh Lakes to the base of Mount Moran, definitely the shuttle boat across Jenny Lake and hike to Hidden Falls, Inspiration Point, and into Cascade Canyon, and a hike to Taggart and Bradley Lakes. The river trips, either float or white water, are great. A fly fishing float trip was awesome. I found the dinner cruise on Jackson Lake not worth the money it cost. Its an awesome area, and felt there was so much left to see and do that we are returning to the same jobs for next summer ;-0
