I'll be looking forward to the responses you get, MAGICX2 - we're also going in January for our DS's first birthday!
So far we have a late breakfast planned at Chef Mickey's on his birthday and we're also thinking about a small family party in our room since DH, DS, and I will be in a 1 bedroom at Boardwalk and we can make a basic dinner and we'll probably order a cake or pick one up at our typical stop at the Target Greatland. My parents will be traveling with us and my grandfather lives in Naples and plans to come up to see Theo for his birthday, so I think it would work well for us to do something in our villa.
I was thinking about a "birthday boy" long-sleeved tee or something for him to wear during the day...I'm not sure, though.
I hope to see some great ideas!
Happy birthday to your DD!!!
