OK fair enough, my house is in Bradenton and I tend to stick to the west coast, obviously been all over the place but like the west better.
If you want a good beach then Siesta Key Beach is my favourite but it is like 2 hours from Orlando.
If you want a good meal in Orlando then check out The Capital Grille, I normally go to the one down in Naples but Orlando is just as good.
Don't forget to at least go to one of the restaurants at Fontainebleau while in Miami, one of the best reasons for going over there in my opinion.
If you haven't booked your night in Miami yet, check out W hotel South Beach, very nice for a night or two.
Have a good time!
