This Walgreens seems to have everything you need for your Vegas destination adventure! I called in a prescription and they had it ready in less than 5 minutes- truly incredible. From your basic cosmetics to skin care, home and snack needs this Walgreens also comes with a fancy dancy clothing section.
If you're trying to get together a safe kit to save yourself from the wrath of Vegas I highly recommend it. Better to walk though in all honesty, if you don't you'll be fighting traffic.
