Asking about the Swimming Pool

A: Is there a swimming pool in this hotel?
B: We don't have a full-sized swimming pool, but we do have individual swim stations.
A: What exactly does that mean?
B: Basically, a swim station is like a treadmill, except instead of running, you swim.
A: That sounds really neat. Is there an extra charge for these swim stations?
B: If you're a registered guest, you have free access to our swim stations.
A: Are the swim stations open 24 hours, like the rest of the gym?
B: To conserve electricity, the stations operate only from 7:00 a.m. till 10:00 p.m.
A: I'll go down there as soon as I can!
B: I don't think you'll be disappointed. People really seem to like the swim stations.
