What activities are there for singles on Costa ships?

I plan on having a cruise alone this summer. And I prefer if it would be a Mediterranean cruising and I only need some info about what activities are there for singles on Costa ships? I need this info for I am considering booking a cabin on one of those Costa ships and since I would be cruising single it is very important to me to book some Costa ship with all those facilities that would fit me. Thanks!

I suggest you than book a cabin on Costa Mediterrane. I was cruising with this ship last summer and I had a great time for it provides wide variety of facilities that are just about to fit perfectly those single ones especially if you love physical activity. So you would have plenty of chance there for fitness and recreation there are 4 pools and 2 of them has a roof so you may swim at whatever the weather is outside. And there are 2 gyms on 2 of the decks with all the facilities you can imagine for having a great work out. And also there is a spa. But besides all this Costa ship is always full of passengers willing to have great time so I bet you could make some new friends there also.
