I believe all pool areas have a sign similar to the one down the page on
This Thread. Also, if you'll do a web search you'll see this topic brought up in a number of different areas. Historically Disney used to allow pool hoping for all on property resorts but this has ceased and only the
DVC members now have that option subject to availability within the pool hopping rules. Many timeshares also offer day use for their members including a number I own at but Disney have never allowed this. They have their internal rules and documentation but I'm not sure there's a location you can find on Disney's website that will answer this question, if there is, maybe someone else can find it for you.
