Well this was fun!
We were given the voucher when we walked into the MGM Hotel, however we had no idea how far we'd have to walk. If you enter off the Strip, the answer is A LONG way. We were supposed to see an un-aired pilot for a tv, however my friend hit the demographic for a marketing strategy so we got to be ushered into another room and seated while she watched and I kinda messed around on the net on my phone.
I can't tell you what we watched, only that it amused me, But it was nice to have free water, a comfy seat and watch a tv show I've not seen.
