At the Dula gym, their "bigger" section is the basketball court. You walk in, see the basketball court and seats. You can't miss it. There are a few side rooms with personal training/ few gym machines, but those are rooms. You have a shower+ bathrooms as well. What I didn't really like about this as a gym, though, is that it's more focused with the court and that there are really small fitness rooms with some machines. This is located in Downtown LV, pass Fremont, and is tricky to get in. It's on Bonanza and you have to turn in before you see it- if you see a sign that points you to a couple places (incl Dula Gym), that's where you turn in. (We came in from the freeway, rather from the Strip).
Air conditioned as well :D
