Yes, don't make my mistake!! Luckily, it was "only" a $63 mistake this time. C'mon free dining!!
I just tried to book the exact same package that I have right now (without being signed up, just to check the current cost) with the S/P/D and it is $201 more than what we're paying for it! I'm glad I called the first morning that the offer was available for the GP.
