We are going just for the day, not staying overnight. Can we leave for a bit and able to come back in? Or once you leave are you out and have to pay again ?

Yes, I can also confirm. With the wrist band you can come and go as you please throughout the day. It is a very relaxed environment in this regard. Have fun!

You will get wrist bands so you can leave and come back in

Yes

Yes. With wrist bands you can come and go all day.
