We are from out of state. Can we invite our friend and their family (from Orlando) to spend time with us at the water park?

Yes, we had family from out of town and we got to go play with them! The people at the gate had no problem with it. They'll just have to give your name and room number. Have fun! The water park is great.

As long as they enter the resort with you , they don't check for it. Ever. They will see your parking pass in your vehicle as you enter the gate.

Yes you can
