My wife and I flew into Orlando the night before the cruise and stayed at a hotel near the airport. We had decided to rent a car to drive to Port Canaveral the next day. We were able to find a car for $40 through Budget. Even after gas and tolls, it was cheaper than the $35 per person shuttle service offered by the cruise line. Plus it gave us the flexibility to stop along the way at a grocery store to get our allotment of wine (1 bottle each) and soda/water (12 bottles each).
The day of the cruise we drove to Port Canaveral, dropped off the rental car, and took their shuttle to the cruise terminal. We arrived at the cruise terminal at 1:30. Embarkation was quick and simple -- we were on the ship by 2:00.
We spent the first several hours exploring the ship, getting acquainted with how to get from place to place. We had an interior state room on level six. It was rather small, but to be expected on a cruise ship. Biggest complaint on the room was that the fridge didn't get very cold, which made it difficult to keep the drinks we brought on-board cool.
Room was really narrow, almost felt claustrophobic without a window. The fridge did not get very cold. We were able to store the suitcase under the bed and utilize the closets for our clothes. The closet with the life vests smelled like sea weed, so we didn't put any of our clothes in that one. The beds were comfortable enough - we were always tired by the time we got back to the room.
