Hi =
Dont forget to get them Happy anniversary buttons!! DH and I also wore anniversary tshirts and got TONS of attention, compliments, congrads etc - it was sooo fun!!! I also think at the front desk you can mention that you would like a call from a character wishing them happy anniversary - they may also deliver a few balloons and a card from the character - just make sure that you call and remind them 48 hours before the day of the event (on our trip last week, they forgot my DH's bday - oh well)
Have a wonderful, special time!!
