Best gym in Vegas?

I'll be visiting LV next month, and will want to get in a couple work-outs between stuffing myself at the buffets. Does anyone have an opinion on their favorite gym in Vegas?

What kind of workouts do you plan to do? Every hotel has treadmills and stationary bikes and some weight machines.

Will you have a car?

I like to do a combination of cardio (treadmill/elliptical) and nautilus/free-weight work-outs. I am debating on renting a car for my trip.

Depending on where you're staying, the workout facilities vary wildly.

On the strip, you'll usually find acceptable facilities at almost all the hotels. Downtown, most of the hotels don't have workout rooms.

Local places - some are very nice, some are pretty sucky.

Tell us where you're staying, and we'll give more detailed info.

I like the gym at Caesars.

Unless you are staying in a dump, I don't really see any reason to not use the workout facilities at your hotel

When we are visiting Vegas, we usually stay at Red Rock or GVR, both have really great fitness rooms. We also belong to 24 Hr. Fitness, so we have the option of going to any of their gyms in the area, and some are nice.
