Great experience here at the Salon in The Golden Nugget.
Train at the gym, do cardio, and they also have a private bathroom n changing area w/ robe and slippers included. There's also a big steam room, dry sauna and whirlpool tub!
And water, trail mix, teas and fruits provided throughout the spa.
*I do wish the gym area was bigger. It's a small room! For a massive Golden Nugget hotel, I find that odd.
