Yep! You can save a gift card or a cc on it so it makes it very easy. You can place the order from anywhere, and once you get to a close proximity of the restaurant, you open it back up and it’ll have the open to click “I’m here, make my food” so you click that and then just find a place to sit nearby and wait until it notifies you that it’s ready for pick up. It will tell you a window number to pick up at. Process will be the same at any QS with mobile order.
when you use mobile order in the parks especially, plan ahead bc you have to choose an arrival time window, and the slots fill up. So I’d order about 90min ahead or so of when you want to actually eat. The resort isn’t as busy, but don’t wait until you’re starving either.
Also, depending on which section you stay in, feel free to use the QS at Riviera. Prima Piatta. It’s really good! We stayed in building 54 Aruba, and were closer to that so that’s what we used most of the time. They have a coffee shop upstairs as well if you’re into that. Also there’s a joffreys at the main skyliner station.
