Just got back from a Galaxy cruise from Baltimore and the parking arrangements are well planned. Just be aware, they only accept cash or Travelers Checks as payment. Also, keep your eyes open for people directing you after you pay your fee. The way that they want you to go to drop off luggage appears to take you away from where the cars are parked but it is arranged in a big circle. FWIW, as we approached the luggage drop point I just popped the trunk and the longshoremen (and women!) removed my bags and I never had to get out of the car. Saw no one seeking or offering tips. Same on the tips on return. However, if you use a porter in the Customs area I think they expect to be tipped. On arriving they shuttle you to the ship in little mini-buses. On return, they use big highway buses so they can put your luggage underneath instead of wrestling with it on board. It is a superbly efficient system. Took us 15 minutes from walking down the gangway to driving from the parking lot.
