It all depends on what you are looking for. Are you traveling with dogs? Then I would suggest 400 or 500 as they are close to the dog park. Do you want to be close to the pool or closer to the marina for boat access. All the loops have something that appeals to people. We like to be close to the dog park and the marina. We stay in either 300 which is a preferred or 500 which is a premium. We have stayed in 800 before and enjoyed it. A map can be found on allears.net with the loop numbers and location. I would also suggest you check out Shan-man's Google Earth. He has put so much work into this that I can't believe one person could be so dedicated, but he is. It can be found on the Camping at Disney main page up at the top. It is fantastic. When you know what you are interested in you can look for threads on various loops that will have pictures. Good luck and have a great time.
