I am taking my 6 children, aged between 11 and 20,to Florida for a week next August, on the way back to Europe from Peru. Stop over airport is Miami. My children want to go to Orlando, naturally, and I want to go to the Keys. Any ideas for combining the two with overnights in Miama on arrival and before departure? We have been to the States once before, for a week in New York. Thank you.
