You can get a rental car from Brad's, who I think is the best car rental company on the island for $40 a day. If you book on-line (www.bradscarrental.com) you'll be likely to get a discount to $35 a day. The shuttle from Island Seas does go to Port Lucaya. Most tourist places are fully recovered from the hurricanes. Some of those that are not may never see the light of day again, and include, besides Pier One:
Royal Oasis (and the area around it, including the International Bazaar, are REALLY hurting)
Garden of the Groves (pretty much leveled)
Club Caribbe (although there are some rumors they may eventually come back)
Taino Beach Resort (to be torn down and rebuilt)
Pirates of the Caribbean Theme Park (to be rebuilt but not until Taino Beach is done, probably 3-4 years)
Hope this helps.
