Does anyone know if you have to call to have it noted on the reservation? I didn't notice a place to do it online. I only saw a spot to note dietary issues. My daughter is also turning 7 during our trip. I plan to have a pin on her shirt, but I don't really want to order a cake because we are not really big on having dessert at a meal, we would rather have treats a few hours later. I thought of maybe ordering a cake for our 'Ohana dinner since we are staying at The Poly and could easily take it to the room. Do they sing happy birthday when they bring it?
