Disney will lock hotel swimming pools overnight - Orlando Sentinel
You may remember a few months ago the child drowning at a value resort's pool at night when the pool was unsupervised by lifeguards. Disney isn't saying that has anything to do with this announcement, but nonetheless:
From now on, WDW resort "feature" pools will not be available after normal hours. Once the lifeguard leaves, the pools will be locked. If there doesn't exist a fence around the pool yet, one will be built. It does mention that the smaller "unguarded" pools will still be open all night. So I already question the consistency/necessity of this decision. I'm not sure what constitutes a feature vs quiet pool... seems like even the side pools at the value resorts are "featurish" with only the moderate+ having completely unthemed "quiet pools."
I can't say pool restriction at the extreme hours of the night is going to be a large impact on anyone's vacation really.. I did enjoy on a couple of nights coming back from an entire day at the parks in the middle of summer and taking a dip even though it was midnight or so.
