We had one in March and it was great! You have a water dispenser and your attendant will add fresh fruits to make “spa” water if you like. You also get refillable drink cups and get soft drinks with them at any quick service that has fountain drinks, and there is a cooler to keep your drinks cold while you go on slides.
You attendant’s phone number will be on a paper at the patio and you can text him drink orders but frankly usually faster just to get drinks yourself. The patio food menu that you can order via your attendant only has large platters (eg whole pizzas, pretzels for four people etc) so we found it more convenient to mobile order what we wanted from the regular quick service restaurants and pick it up ourselves. Everything is easy via mobile order and charges to your credit card directly so you don’t need your magic band if you don’t want it (though you can keep charging to it after check out).
Really what makes the patios great is not food and drink ordering, it is the convenience of a place in the shade with comfy seating that you can return to without worrying about someone moving your stuff to steal the shady spot. It also has a little safe for wallets/phones with chargers in it which is really handy as it meant we did not have to rent a locker. Was really relaxing
