I am hoping for a little input. We will be celebrating my daughter's 16th birthday during our trip in November. We have reserved a Wishes celebration cruise that will be departing from the Grand Floridian. We would like to order a special cake for her from the Grand Floridian bakery. There will be 7 of us in our party (3 adults, 3 teens and a toddler). What size cake would be good for this party size? Also, she has expressed interest in a mad hatter style cake and I am wondering if they are available in smaller sizes. Any help or suggestions are greatly appreciated. Thanks!
