My brother bought the tickets today. They have to be exchanged when activated at WDW I am assuming for the plastic cards with the RDF chip. We won't get the tickets until we arrive in Orlando in May. The tickets do have numbers on them. My 30 day window will be April 13th if going by the day we first check into our resort which is Windsor Hills. When I was considering staying on site and being able to book FP 60 days in advance I called Disney. The Disney cast member said something about using the number off of the back of the tickets. I was explaining my concerns with not having access to the tickets until arrival. How does Disney know when I am at my 30 day window if staying off site? I had to get the discounted tickets due to our budget and it was a great deal. I am now thoroughly confused about getting our FP. I don't want to arrive in Orlando mid May without fast passes.
