US mail; first time I can ever remember getting a pin in the mail. Its an intriguing offer, but I can't easily figure out what its worth. I imagine if you could do it with one adult and two (or three) kids, it would be a great deal, but they don't say if you can. They quote $794 per adult based on double occupancy for 5 nights, 6 days. So presumably they're expecting two adults and two kids, and the deal costs $1588. The room would cost $625 for 5 nights, the 6 day tickets would cost $883.96. The dining plan would cost $611.76. So I think this total package would cost $2120.72. Based on that, this offer saves 532.72, or almost exactly 25%. Not a bad deal, but its only good from March through Mid April; I don't see that as very useful, but I suppose some last minute planners would take advantage of it.
