We are going with the Colorado River & Trail Expeditions CRATE. We are flying ou to Las Vegas the day before, staying at the Best Western, then taking a bus to the canyon. Of course we had to waive everything, but you have to waive everything now-a-days. Some relatives of ours did it last year, and liked it so much, they decided to go again this year, and we decided to go along.
Take a look at the CRATE site:
Grand Canyon Rafting, Colorado River Rafting, Whitewater Rafting thay have a lot of nice canyon rafting trips.
