It's called the Royal Sea package. I must admit, that rolling suitcase was adorable! I so wanted to buy just the suitcase for my daughter but they don't sell it separately. It's called the Princess Royal Rolling Trunk and it's pink. I think it says Disney Fantasy on it but I can't remember. Also, even though the package says the child gets 1 Castle, 1 Under the Sea, and 1 Pirate makeover, the Fairy Godmothers-in-training said you can just pick another Castle or whatever if u didn't want to do Pirate. Basically, they would let u do whichever makeovers u wanted so long as u got your 3 makeovers.
My DD just did the Crown makeover on both the formal and semi-formal nights and my DS did the Royal Knight package on the semi-formal night. My DD wore her own Cinderella and Rapunzel gowns to the BBB during her makeovers.
