This rating is specific to NASCAR weekend and the LVMS Clubhouse seats. We have been treating ourselves to these high-priced seats for several years now, and the NASCAR weekend at LVMS can't be beat. The Clubhouse seating offers excellent catered food on all three days, VERY close parking, a nice indoor clubhouse so you can take a break from the action (or hole up inside if it rains), theatre-style seating with backs and armrests. Free beer, wine, and soft drinks. This is a very fun experience.
Every year, they come closer and closer to getting it "just right" and I would say their biggest chance for improvement is the way the food is laid out - it kind of encourages a long single-file line that is not very efficient. Or, one day there will be a shortage of some item, and they next day they will have tons of it. Like the delivery truck arrived late!
I have been to all kinds of sporting events and find that the NASCAR crowds are some of the most friendly and patient people. The only fights I have ever seen are among the drivers!
Sidebar - A NASCAR race is incredibly LOUD - I honestly do not see HOW anyone can sit there without ear protection. You can rent radio headphones, or at a minimum you should get some of those $2 foam earplugs.
