I'm an Escapee member and have stayed at several of the Rainbow Parks. Co-op parks are for Escapees members only while anybody can stay at a Rainbow Park. Escapees members do get a reduced rate. Couple of the co-ops do not offer monthly rates but all of the Rainbow Parks do. I joined Escapees originally when booking a 2 week stay in Heiskell, TN while we we still just vacation camping. The 2 week non-member cost was more than the 2 week member cost plus the price of the membership dues. Now that we are retired and do much longer stays, we have kept up our Escapees membership.
