So, I'll be the first to admit -- I'm not so good with the maths and ciphering and such. I'm looking to burn some extra points on our upcoming trip and I'm looking at Shark Reef passes. Two passes are listed at 32,500 points and a single pass is 12,500 points. If I needed two passes, is there some reason I shouldn't buy two single passes and save 7,500 points? Am I missing something here? I've looked at the descriptions and don't see any differences between the two.
