Hey Everyone...I have a special occasion to attend in 2 weeks and I am in need of a recommendation to a spa in town. Even if the spa is off the strip. If they have discounts or specials that works for me as well

Encore /  Palazzo /  Green Valley in that order all have great spas.  Most of the other hotels are still very good .. but be aware all the strip spas are very expensive !  99% of their customers are the "nieces"  of their guests.

Since you've been a Vegas resident for many years, I'm sure you realize off-strip spas are more convenient in regard to parking, and their prices are usually much less than hotel spas.

My esthetician just retired, so my advice would be to ask your beautician in hope he/she may be able to recommend someone for you.  Also, Vegas has several wonderful dermatologists, you may want to ask.  I've also added a Yelp list, below, for you to review.  

BTW, I hope you have a great time at your "special occasion."

The spa at South Point is very nice and they offer a locals discount. Prices are more reasonable than the main strip hotel spa's IMO
