We are cruising on 3/15/07, the 8 day Mexican Riviera on the "Spirit". As we will be cruising with a 2 year old, I would like to know how soon upon getting on the ship can we access our cabins? We plan on getting to the pier early so, we will be getting on the ship early. This puts us at right around nap time, I am hoping we can access the cabin sooner than later. Anybody have this info?
