Although my sister and her husband are world travelers this was their first cruise. This was the third cruise for my wife and me (Caribbean & Bahamas).
We visited Inner Harbor before boarding the ship. There was no problem getting on the ship. It was smooth and quick. Go to the open lunch on the ship before going to your quarters. Your luggage will probally be delivered by then. Don't pack any irons, you can't get them on the ship. They hold them for you till you return. The ship was very clean everywhere. The stateroom we had was nice but next time we will upgrade to a balcony suite.
There are no clocks or night lights in the staterooms.... so if you need them.
