I enjoyed the amenities and it was exactly what I needed after a very stressful year.  I was already relaxed while waiting for my appointment and received a top-service massage and facial.  If you are having a facial and want to visit the sauna, jacuzzi or steam room, get there early and do it before.  I did not think about that and thought I would go after, but was told to avoid it after my skin treatment.  I enjoyed the wave room and salt grotto though.  I would take a swimsuit  to enjoy some of the facilities like sauna and steam room if you prefer not to be in a towel.  I would have given it 4 stars, but not pleased with surprise fees or add-ons, so be careful with unwanted add-ons.  For example, I did not request a collagen mask, but she put one on during my facial and then I was charged for it.  I thought it was a part of the facial, but was charged an extra $40 after an already expensive services.  I also had a coupon for a free add-on treatment from the Palazzo, which they acknowledged the coupon on the receipt and also attempted to charge me.  If we stay at the Palazzo or Venetian, I would definitely go back and take advantage of all the amenities there to enjoy, but know to watch out for extra services.
