My husband and I will be getting off a cruise in MIami on a monday in a few weeks, have rented a car for the day. FLy out of FLL at 9:30 pm, we want to travel down the keys, but not more than 2 hours from FLL area. We have been looking at Islamorada as a key to get to. We just want to enjoy the view, lounge in the sun, etc before we head back to MN. Is there public beaches? Places to swim? ANy advice would be great!
