Here's a list I posted over at our Hotel Forum to check out'
Cruises from Fort Lauderdale - Hotels with Shutle Service - Cruise and Play - Fort Lauderdale CVB
The Hyatt Place, Renaissance, & Embassy Suites, are all within walking distance of Harbor shops,with the Hyatt bieng just across a small street seperating them. Here you will find a Publix supermarket restaurants, and, liquor store.
Unless you rent a car, there is no large shopping center close by. If you did decide to rent a car/van for all of you, the car rental shuttle would take you to the pier.
