We've celebrated my last DD's last 2

at WDW (6 & 7). Even though I mentioned it when I made the room ressies, and in my room preference fax sent 4 days before, other than receiving a special "certificate" upon checking in at one of the resorts, the resort, itself, did nothing special.

I guess you have to make a special request.
So, last year I brought decorations to put in the room along with a window marker to use on the window (and mirror), and rental van. I didn't want to rely on the resort to acknowledge her

. That being said, she still had a great time! She wore her Birthday button for a few days and was greeted with "Happy Birthdays" everywhere we went. She was wished a HB by Goofy (on the phone) several times. Several CMs had noticed her button and said she had a phone call. During the 2 times we were there, this happened at Epcot Guest Relations, the lobby of Brown Derby, and in Mousegears at Epcot.
Also, she got special desserts, at the TS restaurants, we ate at. California Grill even had everyone sing to her! She loved it!

.
She had a couple of great birthday moments, all of which (other than my doing room decorations) were random events.
Have a great time! (don't forget to get those buttons!)
