My question is when purchasing the unlimited pass on the day we wanted to use it (instead of in advance or staying at a Deluxe hotel), do they sell out in early March? There are 6 adults traveling, so we'll need two rooms for 2 nights, but only 4 adults ride. I did the math where staying Deluxe definitely would save IF all adults were riders, but it's much cheaper to buy EU for 4 ppl for just one day (or even 2 days) since we will actually have 3 park days to ride everything we want (2 riders will be first timers at USO/IOA).
