Save: Spa

Sundays through Thursdays, nonguests can use Aria’s spa (877/312-2742) for the $30 resort fee. There’s the expected sauna and steam bath, but the ultra-cool salt room and hot-stone beds make you feel like a VIP without having to pay for a treatment.

At Vdara (pictured; 702/590-2474), $50 gets you into the spa and pool, but the better deal is to get a treatment (say, a $30 manicure), which comes with access.
