I was in Vegas for a rat pack era themed wedding. I booked hair appointment to transform into Lauren Bacall. The spa/salon facilities are very nice and the service quick. My stylist immediately knew the look i was after and nailed it. It was pricey to me but probably not so in Vegas. I made the appointment a week ahead of time and don't think you could do a walk-in. On a side note, I was impressed with the hotel and would stay there if ever in Vegas and want to be in the Freemont Street area.
