Does anyone know if it would be cheaper to purchase LOS UPS in advance or to purchase them at the resort. We are staying at BWV in Sept. We will arriving at the hotel around 1pm on Sat. and will leave around 10 AM on the following Sat. We really won't be needing the passes on the last day. I understand that they allow you to drop either the first or last day if purchased at the resort, but you pay full price instead of the advanced discounted price for all the days. Which is cheaper? Anyone know? Thanks so much!
