My son still talks about the surprise Illuminations birthday cruise from the Beach Club boat dock we did when he was 9...it was 4 years ago. He loved the ride to MGM with our very friendly, fun loving driver that happened to be originally from Illinois before he retired in FL which really made it great. DH and DS talked Chicago sports with him.
The birthday cake was awesome (looked great & tasted good) and came with pop/soda too. The view from the boat was great and not having to fight the crowds or get a spot an hour before the start was wonderful. The other boats all sang happy birthday to him. It was fun to cruise past the crowds walking back to the Boardwalk, Beach & Yacht Clubs.
We had originally booked it believing that friends in Tampa would be joining us for the surprise. Unfortunately those plans fell through, which made the ride a little pricey at the time. Now realizing that he still treasures that surprise, it was well worth the $$.
Hope you can find something that will make your DD's day special.
