Pool hopping is a definite "no" and generally frowned upon on these boards.
If pool hopping was allowed, the cooler resort pools would be overly crowded, which would be unfair for the guest paying to use those pools.
Not that anyone flamed the OP, but it is understandable why some people would think that pool hopping is ok. Back in the day (back when there were much fewer resort opions), you could pool hop at the different resorts. Disney Vacation Club guests are still allowed to use different resort pools and I have heard of CMs mistakenly advising guests that pool hopping is ok. Also, I pointed out in another thread, there is a new guidebook out there (I can't remember the name) that not only says that the pool hopping is allowed, but encourages it, pointing out that you can enjoy the better pools without paying the higher resort rates. So it can be pretty confusing for new or returning guests.
