We booked a four night cruise on the Magic for February and plan to spend three days/nights prior to the cruise relaxing at a family friendly resort in the Miami area. Any suggestions for moderately upscale resort that is still "affordable"? Would love the Ritz in Key Biscayne but a bit out of our price range. Would love close to a beach, pool, but with a resort type feel. Willing to be 30-45 min from port if it is a great place and affordable. Any suggestions welcome! Kids are 13 and 11...
