Is it permissible to use the indoor racquetball courts to play tennis. No, not with another person but I would be in there with a tennis racquet and ball rallying against the wall. Please advise. I am using Lifetime Fitness Gym, there are several glass courts and I will be going AFTER HOURS, when there is no wait and no demand for a court.

we play at the YMCA, and just started playing racquetball. Its myself and 2 kids 14, and 8 yrs old. we have the glasses and rackets and correct balls to use. We basically have just been hitting the wall but would like to learn how to really play.
Also how many calories can you burn from playing? Especially when eating properly now and drinking water, really working hard on losing weight.
