Ok 2nd San Diego thread, but different!

It looks like I will be in San Diego in a few weeks for a work conference(fly in jan 15th fly out late jan 18th) and am looking for ideas to keep up fitness besides running... even though I will probably end up running, since it is free and on my time schedule.

Are there any good indoor spin facilities maybe that simulate the road/(computrainer would be ideal but I won't have a bike, so it doesn't work out....) or lap pools with open swim?

I will be staying near the Convention Center and will not have access to a car.
