If you're in Las Vegas, this is a MUST! My boyfriend and I did the Zoomline, the upper line, which makes you feel like you're flying over Freemont Street and in my opinion, the best way to see Freemont Street without having to deal with the enormous crowds in the evening. Our "flight" time was at 10pm, but we didn't go until almost 40 minutes later, so don't assume because your ticket says a certain time, you'll be going....prepare to wait, for awhile. I would definitely spend the extra $$ and do this at night - it's worth ti!
