No apologies here - I'm a giant KISS fan, so of course this rates high!
To be honest, the course was really nice. It's in great shape and the hole layouts are unique. I loved the music (executed well by a DJ with shout-outs to groups in attendance) and the black-light atmosphere. Our group took our time during the round - checking out the layout of each hole and calculating what the best shots would be. Our friends ahead of us blew through the course, but I think we had more fun really soaking it in. We didn't slow things down - the groups behind us were several holes behind and never rode our heels.
The gift shop was decent, but lacked some of the quick/easy gifts to pick up just to say "yeah, I was there". Key chains for $15 didn't seem reasonable, even for Vegas...even for KISS... The autographed memorabilia was sweet - and yes, they'll ship it for you.
The staff were great to our group - very courteous and helpful. Even the non-KISS fans in the group had fun.
