All of the resorts do have nice pools, but the themes vary, and the value resorts don't have slides. So if a fancy pool is important, be sure to stay in the corresponding resort. You can, however play in the PO-R pool while staying in PO-FQ and visa versa, because they are sister resorts. I think it is only fair that those who pay the price to stay in a certain resort should have access to that pool, and some pools are very crowded, even with access being limited to resort guests only.
