change of plans

what we are thinkiing of now is and more than likely to be the plan with a few minor tweaks here and there :-

fly into MIA
drive to maybe fort lauderdale, uncle suggested marriott residence inn plantation, stay next day to have a look around.
have breakfast next day then leave for orlando
book into villa for the 2 weeks stay, or however long we choose to stay there
2 nights AKL
then whatever days are left we move down to the gulf coast somewhere other than cape coma

drive back to MIA for the flight home

suggestions for gulf coast stay would be more than welcome as we have only been to clearwater back in 2000

ive heard good things about sarasota and st petes. ideas on those???
