Cabanas was open pretty late in the afternoon last week on the Dream. Past 2:00, so you should hopefully be good. The tests were pretty quick too, results in 15 -20 minutes (we had B2B and both times it was quick). So if you arrive to test at 1:30, there’s likely going to be a line if you are parking at the lot or potentially a line at the tents if you are not parking there. I think you will be fine for lunch at Cabanas, but dont forget at the pool deck restaurants, one place has sandwiches, salads and fruits. So you dont have to have the greasy foods from the grill or pizza. The grill also has grilled chicken breasts as well.
