DH and I are going on our first Disney cruise and we unknowingly booked HOTHS. I'm excited as I love Halloween, but I have a question about costumes. Because we have friends who host a huge Halloween party every year we have a lot of great costumes, but only one is Disney themed. Will we be out of place in non-Disney costumes? I'm guessing most people will be in Disney themed costumes, but I wanted to ask if anyone has experience with HOTHS and non-Disney costumes.
