Today we are at sea all day in international waters in the Caribbean. This means we get to explore the ship and watch the ocean go by.
And we get to explore on-board activities- fitness classes, art classes, ballroom dance classes, singing groups, casino, pool, spa, and, of course, eating.
I did take a fitness class in the morning and in the afternoon I was really sore.
Our room is on the 7th deck, the fitness center is on the 9th, the library is on the 10th, and places to eat are on the 5th and 9th deck. So there is plenty of opportunity to take the stairs which I do (sometimes).
