Pennbriar is known for their tennis courts and often hosts tennis tournaments. They offer great summer memberships that are absolutely wonderful for the kids who have nothing to do while mom and dad work and they're out of school all summer. It keeps them busy and active and your only worry it getting them there and picking them up.
They have a well kept indoor pool, nice outdoor pool that opens in the summer, tennis courts, clean locker rooms and a pleasant staff. While like most health clubs they can be somewhat pricey but to be honest I don't think they're overpriced in comparison to others. They also seem to be very well staffed, which a lot of other clubs can't say. If you need help on various workout machines there's almost always someone nearby that can come to your aid.
