I recently held a meeting for an organization I am affiliated with at UNLV's Student Union. I had an extremely positive experience both in booking the conference room and hosting the meeting with UNLV.
I worked with Suzie and Lonnie in actually booking the room. Both were always very pleasant, informative, and helpful in selecting the best room for our event and equipping our room with everything we would need to have a successful event.
While I did not venture far into the campus, the Student Union itself is great. While we did not cater food, the Student Union has an array of fast food/dining options on the floor level for your guests to choose from. There is also other restaurants and coffee spots across the street.
Our conference room was set up perfectly and was very comfy. I believe that all of us had a very positive experience throughout the meeting. I would highly recommend this place!
