I had a great experience at this spa while staying at the Luxor over the past couple of days.
I had a deep tissue and also the scalp and shoulder massage and both of those were great, exactly what I needed while on vacation. Check-in was quick and easy, I was attended to promptly and politely by all staff.
I also used the whirlpool, sauna, steam room, and showers in the spa during my stay. I found the atmosphere to be very serene and calming. I often had an area to myself and a couple of times were just a couple of others were around. Overall, my experience at the spa was great and I'd recommend anyone get a treatment or just pay for the day pass while at the Luxor.
Is this the most luxurious spa in Vegas? No. Is the Luxor the most luxurious hotel in Vegas? No. If you can adjust your expectations, you can really enjoy this spa.
