My dd will be celebrating her 13th at HDDR in Oct, with a friend who turns 13 two days later. Dd really wanted her 13th to be at HDDR, so is very excited. But, when I looked into having a special cake for the girls at the end of dinner, I found that HDDR isn't all that crazy about doing that. I understand that they do make announcements of those who are having birthdays, and sometimes a birthday person gets selected to part of the stage show.
We are going to have a 'birthday' lunch at Grand Floridian Cafe earlier that day, with a special cake.
