I see tennis courts across the street. Are those for public use? If so, do you have tennis rackets available (so we don't have to bring them on the plane)?
The City Park does indeed have tennis courts which you may use. We are a small hotel and do not have room to store things of that size however, there are local sports stores and a K-Mart which might serve your needs.
