Thank you Jesse. Looks like the train ride is a great option. I looked in to shuttles from FLL to the host hotel and it was going to be $20 a head plus tax and tip. That would have put us out the cost of another plane ticket.
No problem. It looked like a pretty good option for searching for competitive rates. I have never taken that train, though, so be sure to do your homework.
Don't forget that Frontier, JetBlue and Southwest both service West Palm Beach, and I have found http://www.kayak.com
