Any time I am considering a new RV park, the first place I go is
rvparkreviews.com for a quick check of others experiences there.
But take some of the comments with a grain of salt. If the majority of the reviews give 8, 9, 10 and a couple give 2 or 3, you can usually discount the low reviews. Often as not it was due to some minor issue that person took personally. Likewise if the majority of the reviews are 1, 2, 3, and a couple are 9 and 10 you can likely discount the high reviews also.
