What about regular lap swimming or doing your own exercises during open swim? You might be able to find a time when you can go on your own.
If you are in a larger city, Aqua Zumba is worth looking into...though it does not seem to be widely available.
Nobody else can do this for you--put it on your calendar and GO.
