There are only two partial hookup loops. They are used primarily for tents and popup campers. They are the 1500 and 2000 I believe. Some people like these loops a lot. I have a popup camper and have never used a partial site. I have stayed in the 100, 200, 800, and 1400 loops. I don't know which sites are more private, but most are somewhat private, anyhow. The 800, 900, and 1000 are very close to the meadow trading post. The 100, 200, and 400 are very close to the settlement. These would be my preference. I never tell the reservation phone operator that I have a popup. It is a "24 foot camping trailer". They always try to put me on a partial site as soon as they hear "popup".
No matter what loop you get, you will enjoy your stay. Someone else will surely comment more on the partial sites.
