A: Fast lap is not worth the money. First they don't take GROUPON on Saturday, even though the place was empty and no where on the GROUPON did it state this. Secondly the staff was rude, probably another reason they were empty. There are better Kart racing in Vegas. Go to another place.

A: This place is my wet dream. It's so big I could spend hours there. Twice a year when I go to Vegas this is a mandatory stop for me. They always have 12 month no only financing, and sometimes have 24 month financing. I can't tell you how close I've come to justifying why a $10,000 Concord watch is 'worth it' and doing the math in my head. Next time I promise I'll actually step up and buy something. Everything from Fossil to Rolex to Breitling to Concord to IWC to Jacquet Droz... $50 to $200,000! I did overhear the salepeople comparing their sales rankings however and how one was upset he didn't win in 2008. So obviously there is room for negotiation, and I plan on using just that tactic when I go back. Not sure the markup, but I'd guess there is quite a large room for negotiation. Heck it's Vegas. Name your price and if they let you walk out you know you've offered too low. Eventually they will concede and name the bottom line price. Salespeople are trained to look right at your wrist and see what you've got on. They play a game to see if they can spot a replica/fake, so if you try to pass it on them, they won't call you out on it, but surely they will be laughing inside. Try walking to the back row (ultra high end greatr than $10,000) and see how quickly they come to you. Depending on how you are dressed you may end up waiting a while. When it comes my time to buy that Concord I'll come dressed as cheaply as I can so they don't try to upsell me.

A:
Very annoyed. Booked birthday for 10am. For 15 5 and 6 year olds. The place is closed. Did not mention that when we made booking.
