My wife, adult daughter and I traveled from Cape Liberty on the August 28th sailing of the Explorer of the Seas on a nine day Canadian trip. Ports of call included Sydney, NS, Charlottetown, PEI, Quebec City and Halifax, NS.
Checking in at Cape Liberty was relatively fast and easy. The bags get dropped near the terminal and while my wife and daughter waited for me to return; I parked the car within walking distance of the terminal. There are a large number of handicap parking spaces in the parking area, but the $16 per day charge applied to all.
As Diamond members there was a separate line and we were through with the formalities and on the shuttle to the ship within 20 minutes of arrival at the terminal.
