Highly recommend - they are thorough when it comes to the details of the dry suits, the raft, safety instructions, paddling commands, visual commands, capsizing instructions - by the time you hit the water, you have everything you need to know to have a fun filled time flying over rapids, navigating your way through canyons, and watching the beautiful scenery go by. The 3 canyon rapids were the way to go - heck, the Class 5 were no problem as we had already capsized in Class 4 - lol! Fun times - hope to get there again next time I am in Alaska! Thanks guys!
