Yes to both the cab driver and the people you give your luggage to at the pier. Cab driver will depend upon what your fare is and a few bucks for each piece of luggage you check in at the pier.
When you check-in at the pier, ask about the auto tipping, they should be able to set it up. Also a good idea to get into the Royal Caribbean web site and fill in all your information. That will make embarkment easier and quicker.
Hope you enjoy your first cruise. What ship are you on?
