We will be visiting Monument Valley in October.. driving from Page and arriving late morning.. We have already booked the Navajo Spirit Monument Valley tour at 1:00 pm.. and then we are staying at the View hotel for the night. I just read about the Mystery Valley tour and thought it sounded interesting also.. Which one is better? Or should we do the 1:00 pm MV tour and then do the sunset Mystery Valley tour also? Or would that be too tiring (he is 73 and I am 59)? We have never been to Monument Valley before, and my husband has always wanted to go there.. from seeing it in so many John Wayne movies.. LOL. This will be our only visit.. so I want to make it as special as possible.. Thanks!
