I'm outside of Moab. According to two sources I read, the NPS is considering timed entry into parks to reduce over crowding. The articles don't go into specifics about which parks so keep your ear to the ground.
It mentions using recreation.gov to obtain a 'time slot'. Watch this development in case something like that affects your plan. You may need to make advanced reservations, just as you do for campsites. I hate having to be 'somewhere' on a specific date, but it's what Rving has amounted to. Would be a shame to arrive somewhere, only to find out you can't enjoy the reason you came in the first place - like the hoarding that takes place in State and NPS campgrounds on weekends
