Has anyone vacationed in the Florida Keys around the first of the year? Curious if the water and weather is warm enough for swiming, for kids. Thinking of going for a week but wondered if there was enough to do around there to entertain 2 kids around 10 years old for a week. Want someplace warm and safe on a nice beach around the first of the year for a vacation if anyone has other suggestions. Not sure I want to do international because I would have to get the kids passports.
