We are planning a trip on Zephyr to Grand Junction in early May. We will stay at Grand Junction for a couple days and then drive to Moab, Utah and visit Arches and Canyonlands National Parks and then on to Monument Valley. We have been on the Zephyr before and we have been to Monument Valley before (about 17 years ago before the hotel was built there) but the rest is new territory for us. We will probably want to go on a tour at Monument Valley as we did during our prior trip but I imagine the tour operators have changed (and I can't recall who gave us the tour the last time). Any advice would be appreciated. Thanks.
