It is very easy to get a taxi at the port. Just have a port grab your luggage and he/she will navigate through the traffic, right to the cabs. It's worth the tip to have someone else lug the luggage while you mind the kids.
A cab is around $70 but I would check into a shuttle service. There has been one named by a few people on the boards, including our moderator Trip.
I'll bet she'll be by in a bit and let you know the name.

Any cab should take you to Ft Lauderdale, and yes, $65 to $75 is right. There are car services that are cheaper BUT most of them are cheaper because they take multiple passengers.
I once got a car service from Ft lauderdale to South Beach for $50, but the ride took over two hours because we had to drop off three other riders on the way and I didn't arrive until after midnight. The taxi is far more convenient unless you have assurance you are the only riders.

I can't remember which company we used to take us from the hotel to the pier - and the pier to the airport, but we had no problem at the end of the cruise. The driver told me to call him as we were going thru customs/immigration. There were 20 of us, so I waited until we were all through and had our luggage (just in case someone got hung up). As I was on the cell phone talking to him, he walked up right behind me!! If I can find the name of the company - I will post it here for you.
