we had extra long here because we had to skip key west. walked around square in the morning and enjoyed shopping. Went back to eat lunch on ship and change for afternoon excusrion to swim with dolphins - great!
No cruises added
Don't go in march with kids - boat caters to the 21-28 crowd. Not enough activities for kids. one pool but around bar area, all hot tubs over 21. Go for the flex time dining. Never had to wait more than 5 minutes to get a seat. It was nice going at our leisure.
