That is a problem. Campers paying $30 a night should not have access to the same facilities as someone paying $200+ a night. I remember the last time we stayed at the WL, our buses would often stop at the campground on the way to Epcot or any of the other parks. It was way out of the way, and very annoying. Often the buses were jam packed with campers. I don't think a deluxe resort should have to share a bus with a campground. Nothing against campers, I enjoy camping too. I just think that a deluxe resort guest should have better service. I haven't stayed at the WL since.
However, as already mentioned,
DVC members are allowed to pool hop.
