We are going on our first cruise. We fly into Miami at noon on Wednesday and our cruise is scheduled to leave noon on Thursday. We will have our 12 year old with us. Can anyone suggest ideas for the 24 hours before? Also, what time should we plan on being back for the cruise? We had thoughts of traveling to Key Largo- but looking for any suggestions anyone might have. Super excited, but also a bit anxious as not sure exactly what to expect. (one of those people who usually arrive early in order to feel on time)

We are flying into Miami the day before our cruise. Looking for suggestions on where/how to spend the 24 hours before we need to be at the port?
