I've travelled all over but this by far the most challenging trip I've tried to plan. Would like 2 days in Vegas, go to both rims plus GC west, Hoover Dam, Sedona, in 10 days after labor day. Is this too much to try? Would love to stay on north rim, don't mind hotel hopping. Best to fly into Vegas? Flagstaff? Many times we go with first nite reservations and wing it in-between. I'm gathering this might not be doable as we might end up sleeping in the car. We like flexibility where possible. Thanks for any help & I'm sure there will be more questions.
