I've never been to Miami as an adult , so since we wanted to do a (precruise) day of sightseeing , I was in the same boat as you re / hotel . After looking at alot of posts at cruisecritic.com re / miami hotels . And going to travel and hotel websites . I ( now having an idea about costs ) went lastly to AAA south auto club that Ibelong to and found some , called a few , and at last made a good deal and set a reservation . Good luck , it takes some research .
