I have stayed at both places for a week each with small kids, FWIW-KCB is one of a kind for a private, safe area and very cool. I stayed in Tavernier for a week with my family and another family. Not all SeaCraft members are currently reminded or ever experienced the needs of mom and kids being happy for a week on vacation. North Keys have closer access to multiple kid friendly oceanside boatable locations / fishing offshore. Throw in the landside activities like the waterpark, Pennekamp, Dairy queen, ect. and MOM and KIDS will be HAPPY.
Then YOU can enjoy what you want to do THE MOST!
