In the Abacos I can think of several places to meet up with families with kids
Treasure Cay- Anchor
in the big basin in front of the marina and it costs something like $10/d to use the dinghy dock
, pool and showers. Families often hang around the pool.
Nippers Pig Roast- Every Sunday Nippers on Great Guana Cay does a pig roast. Lots of families there.
Room- The Jib
Room at Marsh Harbor Marina used to do an all the rum
you can drink special on Thursday afternoon and participants brought a covered dish to share. Don't be put off by the booze, lots of families were there.
Although I haven't been to the Exumas
, I understand that Georgetown
has almost every social activity you can think of: volley ball games, softball, etc.
