I would call them and ask....we did just that stopped by and asked the front desk person if we could look around they gave us wrist bands to put on and away we went, we were there for quite awhile because my little guy wanted to see the bucket of slime drop and we still had around a 1/2 hr or more to go before it dropped again so we sat by the pool and waited after we looked around.
When we went it was a few years ago but they did have the security guard at a gate and we just told them what we wanted to do and they let us thru so unless they have changed alot I would call and ask..It would be in their best interested to let you look around who knows you may love it and want to stay there the time you visit Orlando.
