Like many posters, I too was disappointed that the FD extension excluded my travel dates of Oct. 14-19th. I was planning on going whether or not I got FD, so my hopes weren't dashed too much, but it still bummed me out a little, UNTIL....
Yesterday morning I decided to call and see if I had any PINs. The first CM I spoke with said I had a PIN. In my excitement, and stupidity, I said "awesome, I'll have my TA get it applied to my ressie." and then hung up. LOL
About 15 minutes later, I realized I knew nothing about the PIN and started thinking about blackout dates. So I called back and spoke with another CM. This one told me I actually had TWO PINs, one for 40% off room and one for FD. I told her my travel dates, and she came back with the unfortunate news that neither PIN would work with those dates. So I go back to being semi-bummed.
Well, last night, after reading many posts about people having PINs they can't use until July 13th, I decide to call one more time (third time's a charm, right?). I spoke with an awesome CM named Ashton. He was looked for a long while and finally said I have a THIRD PIN attached to my name and this was another FD one and that it would definitely work for my travel dates. He even attempted to go into my ressie and apply it, but was unable due to it being booked by my TA. He gave me the code to give to my TA, but then said "Oh wait, your TA won't be able to do it until 7/13." and that "an official email should be going to you around that time." Needless to say I was ecstatic! I immediately started calculating the savings and whether or not I want to upgrade to a mod, since with FD it'll be around the same price as staying at POP and paying for FD. I decided to stay at POP again and save the $$$ since things are tight right now.
Anyway, the moral of the story is to don't give up. Call three times a day if you have to. I called 3 different times and got 3 different results, each one better than the one before it.
