We just returned from the Canyonlands tour. The departure times from the national parks are well designed. You leave Grand Canyon, Bryce and Zion after lunch. That gives you time to get up for sunrise, take some walks and maybe lunch before heading out. For arrival in the parks they drop you off at the visitor center while the bus and guide go to the hotel to register you. When they return your keys are on your seats and your luggage in is your room. There is no waiting. Everything worked very smoothly on our trip.
