Pretty awesome. Its actually one of the cheapest expenses in Vegas. Its nice to walk around, but man the blocks are HUGE. And my stilettos are too cute to walk 10 miles in.
The monorail will make one stop for a couple of hotels, so check out the map before you hop on. You'll still walk a little ways for most stops since the rail lands across the street or a block away.
Well worth it. A block is nothing compared to a mile - or a mile long cab line.
