Have stayed at all three and now own lots in Sand Hills Resort which is by far the nicest of the three. Yes it is the furthest away but half the fun is the multiple ways to get to the lake or choke cherry hill , and plus you can cross over the road from camp and there is a whole other dune system that goes on for miles with no big climbers , but a vast system of medium hills & rollers. The best part of the (2) main full hook up resorts is that at Sand Hills your right at the dune entrance & at Idaho's resort you have to ride down a long private entrance corridor w/ posted speed limits that are enforced by a crotchety old fart that likes to scare kids with his bitter attitude. Either way go and enjoy yourself it is the most fun dune system I have been to ( Glamis , Dumont , Oregon , Utah , Nv--so far ) because it isn't over crowded , has a lake ( about waist deep at the deepest ) and in the heat of our NV / CA dune summers it's a refreshing change. PS one of your nights go into town w/ the Fam & eat at the pizza buffet parlor ( Pizza pie café )--well worth it
