My present for my baby niece's updoming birthday is to treating her and my sister/ BiL for 2 nights at HKDL. On the other hand, I am going for a week in DLR and D23 Expo, we are staying at Grand Cal. Is there anyway I can get a birthday card and have all the characters sign on it for my niece? If I drop off a card at the hotel front desk, will they help me get this done? Has anyone requested this before?
