I will be going twice this summer to both parks. The first time with a few friends and the second time w/ my family. If I purchase the 169.00 2-Park Preferred Pass deal I will save form my second trip + meal discounts both times. My question is when I purchase my friends tickets and later my family members tickets, do I have to purchase them at the gate to get the 15 % discount? If I do, would it not be better deal to get the 89.00/5 day deal for the friends now on-line and hope the 89.00 is still around for my family later. Either way, since I will be there twice this summer I cannot go wrong with the 169.00. Any suggestions?
