coming to miami from the uk in april staying five nights before we head off on a cruise. Weve been told south beach is the best place to stay. There is 4 adults and a child aged 12. Want a lively area and accomodation. Would we be best in two seperate rooms or would it be cheaper to share. Also can anyone recommend a cheap hotel or an apartment. Think I would prefer an hotel with a pool but dont want to be paying a fortune. Help please.... thanks.
