Aimcat, we're 45 and 43 (but I like to think we have a 30's mentality).
There are basically not activities most of the day. The only activities were the like of play bingo, learn about our next port, secrets of diamonds (to try to sell you something) and learn about some fitness program (to try to sell you something again).
But that would only be a minor problem only on sea days and it's a great moment to indulge yourself on the pool, jacuzzi, the great buffet at Lido, some movies in your room.
When it speeds up is at 5 pm altough it depends of the like of music you prefer. There are 2 or 3 classic music plays of about 40 minutes each. The amazing and dynamic piano duo and the rock band alternates playing 3 shows each one of 45 minutes. And the BB King Blues Club has music to dance beginning I think at 9 pm.
The shows at the theater are so so, with the exception of Humanity which was very good.
The bars were animated until about 11:30 pm.
