Had a wonderful experience at the Spa at Trump. It's a beautiful, luxurious spa. I had the hot stone massage and it was so good! My therapist did a great job as I was so relaxed during and after the massage. Also, I found out that if you stay at the Trump and receive a treatment, they take off $25 off the total cost.
Definitely arrive early (they suggest 30 minutes before your appointment) so that you can enjoy the sauna and steam room.
