My husband and I are driving from Lake Powell to Grand Canyon Tuesday May 14 leaving Lake Powell resort around 10AM. We know about the detour. Should we enter the Grand Canyon probably around 3PM from the East Entrance and drive along the Desert View Drive stopping at viewpoints or go in the South Entrance? We are staying Tuesday and Wed night at Yavapai. I think it makes sense to come in the East Entrance since we're coming from that direction but at that time are the crowds or sun going to be a problem. After the Grand Canyon, on Thursday we drive back towards Phoenix and fly out Friday afternoon. Thanks for your help.
