Can you swim in the Walt Disney World resorts’ pools? How do they know if you are not a guest?

I’m planning a trip to WDW and I’ve seen the pools at their resorts on property – they are amazing but we cannot afford to stay at any of them, are we allowed to swim in their pools? If not, do they check to see if you are a registered guest?

The pools on disney resort property are designed for quest use only. I have never been to a pool at a resort I was not staying at – but – I don’t recall ever being ask either. In fact – you are not supposed to use pools at resorts other than the one you are staying at. They do not require your key to the world to get in the gates and no wrist bands except extra hours in the park (which as of last year are no longer used, just room keys shown)
It’s your gamble but how embarassing if you get caught.
It’s not really that much more expensive to stay on property, especially at a resort such as all stars -plus the transportation and added hours benefits are very nice to have.
Good luck and have fun.
