It was alright. Although something about the new "Celebration" thing seems less gimmicky somehow. I mean, you're already a winner if you just get in the park for free on your b-day.
I just can't help but wonder if the promos are ever going to stop. They're not super-intrusive or anything, but IIRC they weren't doing these things before 2005, except every 5 years when the park turns 30/35/40/45 etc... Ever since the 50th they've been doing some sort of "event" thing annually.
I thought the YOMD was pretty fun. Since I had a Premium AP, it was fun going almost everyday during the summer for pin-trading and looking out for the CM giving out the prizes. The only Dream item I didn't get was the lanyard and of course, the dream suite and the Mickey penthouse prizes. Just over the period that Disney held the celebration, I have over 20 Dream Fastpasses and 15 dream hats. Anyways, it was awesome that the CMs handed out "free" stuff.
