My husband and I will be driving from Naples after visiting family for 2-4 nights with our twins that are 17 yo girls and a 10 yo son. We have no plans. Any suggestions? They love the beach and all types of water activities. They love to shop. Would a drive down thwe keys be good or maybe venture north? How about South Beach? We would like a 3,4, or 5 star hotel. Breakfasts, etc like an embassy or a suites hotel would be great.Thanks in advance.
