As usual, I have consulted Trip Advisor for suggestions on HOW to visit the National Parks of Utah.... very helpful! There was even a post called "The Best Week of Your Life" with detailed information on travel between the parks..... We have decided to fly into Salt Lake City, then follow the roads through the parks from East back toward the West and end up flying out of Las Vegas..... The room reservations have been challenging.... I started planning back in February for our September trip and many locations were already booked. As suggested by Trip Advisor forums, I have checked back at some of them and found availability.... here's hoping I've cancelled all the duplicates and have NOT double booked! Our theory is that once school goes back all over the country, we will be traveling with LOTS of other retirees!
