One of the employee perks at Grand Teton Lodge Company is float trips. I went on one Monday, and had a great time. The guide's name is Mike, and he was so smooth in his commentary, jokes, and presentation I could only marvel that his enthusiasm doesn't wane with so much practice.
There were seven guests, myself, and Mike. He kept the boat totally under control while standing up and giving facts as well.
Monday was a beautiful day for the trip, which took three hours. The next couple days were interspersed with snow and rain. They have tarps and rain gear to protect the clients, bringing everything back to the laundromat to dry it out in that event.
Other perks with this company include horseback riding, bus tour to Yellowstone, and bus Tour of the Grand Tetons.
