Stay in the park and avoid the entry station every day, but bring lots of i
This park is in the northern part of Arches NP so you're 30 minutes or so from Moab. If you need ice, it means a trip to Moab when your ice melts. Surprisingly, Moab Ice is not in the park. Would be nice if they added a cooler at the campground or Visitor Center. Dead Horse Point SP near Canyonlands had Moab Ice. Yeah, it was $4/bag but that's better than a drive to Moab. I expect a national park to have ice.
Enough of my griping - that's really my only complaint. Park has water and bathrooms. Get your shower at the rec center in Moab for $5 (or $7 for a workout/shower, $5 for over 55).
Generators are allowed 8 to 10 am and 4 to 8 pm. There's always that guy who likes to stretch it. Camp hosts should be all over those people. Other than that, it was very quiet.
There are several arches nearby in Devil's Garden if you want to hike. Double O is the most challenging arch in that area. Not sure if Tapestry, Broken Arch and Sand Dune are part of Devil's Garden, but they are accessible at the far end of the campground and are nice hikes.
