This service is $8 for 24 hours or $6 for 2 hours if you only want the pass for one day. Hmm which makes more sense to purchase...?
Also it's nice space-wise because it's a double-decker but sadly you can't see out the windows unless you sit in the front because the while bus is covered in ads.
I got on and this couple was fighting loudly so bring headphones and an mp3 player. Also other reviewers said it takes a while to get to the main parts of the strip and I can see why; just one stop later, cops apprehended a guy on the bus, 25 new people boarded, and 10 minutes had passed. It's okay for me though because I'm used to public transit like this and I'm tired so I'll sleep off my trip down to the Luxor no problem. :)
