Walgreens at the Venetian Hotel.
This is my absolute favorite Walgreens in the whole wide world! WHY? you may ask... because they have WHITE CHERRY ICEE!!! They hardly sell that flavor anywhere unless you're at a movie theater or theme park and here they sell if or cheap! About $2!!!
This Walgreens also have a vast assortment of ALCOHOL like crazy amounts! I feel like everyone goes here to buy sh*t for pre-gaming.
The store is super huge and will pretty much carry all your necessities, toiletries, souvenirs etc. check this place out!
