Hi Kim, I am also a plus size. I dressed like a Nurse last year. This year I am dressing like a Pirate. If you really don't want to dress up for Halloween I suggest you dress up in the colors of Orange and Black and wear Halloween jewelry. I know you will look good and fit in also.
YES, ALMOST EVERYBODY DRESSES UP FOR HALLOWEEN. IT IS TOTALLY AWSOME!! You must take photos.
Holiday Inn is just across the street from the pre-cruise party at the International Market Place and only 5 minutes from the cruiseport. Luci
