We redeemed GAD at:
DHS for 1 day ticket for DD8 and upgraded to park hopper 8 day. No issues was easy but we were about 5 deep in line in the morning (on Sat) and it took about 20 minutes.
MK for GAD FP on Monday, easy took about 5 minutes, no issues. got FP cards for 4. We used them for FP for Space Mtn, Splash, and Big Thunder, then the Daisy's for 3 rides on Buzz, worked out great as line was 20-25 min each time.
DHS for GAD FP on Friday (5/28) went about 10 am, only one person in line in front of us took about 5-10 minutes (guest services rep was new).Used 3 at TSM, 2 at Star Tours and gave away the third Star Tours once was SWW so FP was being used there and was usually about 2-3 hours away, line was running 20-50 minutes so good use of Daisy FP for Star Tours. Was well worth the time and investment in GAD opportunitye for the TSM FP's alone, they were out by the time we got there at 1015 that morning.
