What to pack for The Cosmopolitan and a Las Vegas Strip trip
Pack ID, credit card, and a reservation confirmation first; then basics for Las Vegas heat (light daytime clothes, a swimsuit, sun protection) and smarter evening outfits for restaurants, bars, and shows. Include chargers, a small daypack, any medications, and items for pool or spa use—note The Cosmopolitan Of Las Vegas requires a 21+ adult for check-in and some 21+ areas like Marquee Dayclub.

Spa, fitness, and active items
If you plan to use Sahra Spa, Salon & Hammam or the fitness centers, pack workout clothes and any personal items you prefer (the spa provides basics but you may want your own robe or flip-flops). Sahra Spa services are generally available to guests 18 and older; salon services may accept younger guests with an adult.
