I dropped in for a class while visiting Vegas for a conference and I'm very glad I chose CFME. It must be "the" hotspot for visiting crossfitters as I got in the cab with my Rogue shirt on and the cabbie knew exactly where I was going! :) This place is huge and has probably the best collection of equipment I've seen. The staff was extremely helpful and knowledgeable. The WOD was great and pushed the entire class to our limit. The check-in/drop-in policy is very clear and concise. Everything can be scheduled online. The best part (which I unfortunately didn't get to take advantage of) was that once you've dropped in for a session, you are able to come back for $5 per class for the remainder of the week. Next time I'm in town for longer I will certainly take advantage of that option. This place is great!
