Hey crgoode,
Three of us are also going to be in Ft. Lauderdale after Christmas. As I understand it, most of the good diving is further north (Pompano or Dearfield Beach). Unfortunately, we don't have the time to make this trip so I found an operator based in Ft. Lauderdale. Don't know whether they are any good, but seemed the only option. Here is the information...
Brownies
1530 Cordova Rd.
Ft. Lauderdale
(954) 524.2112
We are booked with them for Thursday, 1/2. If your still in town we may need more divers since there are only three of us and the op said they would either need a fourth, or we pay the extra.
