There is a difference between 1500 and 2000.
1500 is an older loop and the sand pads are bigger than the full hookup loops, but 2000 loop has even bigger sand pads than 1500.
1500 is right across the street from Meadows Trading Post, Pool, Bike Barn, and Campfire area. It is a Great location. There are only about 36 sites in 1500 and it only has one comfort station, but it is rarely crowded and not too far of a walk from any site.
2000 is a huge loop with at least 60-plus sites. 2000 has two comfort stations, but it is quite possible to be a good hike from a comfort station. It is also a bit more isolated, and the bus route that 2000 is on does not go by the Meadows area, so you need to take two buses to get to the campfire, Meadows Trading Post, Bike Barn, or pool, or figure out where to get off to walk to Meadows. Having a golf cart or bicycles will alleviate that.
