When we stayed at the Sequoia Lodge (22 - 31st July) the pool didn't open til 3pm every day, the outside pool was open as it was so hot. We only found the opening times out by walking down there at half past 2 for a swim only to be told by someone outside that it now only opened at 3pm.
We stayed at Newport Bay last year and used the pool everyday as a break from the parks, this time we didn't, sounds daft as we were there such a long time but it's how it worked out, we used to get back lie on the bed and fall asleep!!
