The Preferred loops are 100,200 and 300 which is the pet loop. They are located close to the marina. The Premiums are 400 to 1400 off the top of my head, they are bigger sites for larger trailers and RV's. You can request a loop but may not always get it. They do try their best but sometimes it doesn't happen. We requested 400 last year and ended in 1400, was nice though as it was close to the campfire and the meadows. Below is a list of the loops.
