My personal favorite hotel of Las Vegas is the Cosmopolitan! Awesome room, excellent service and cleanliness WOW!
Their staff members do go out of their way to make sure everything is smoooth for you. The best part is the Bellman working outside actually recognize their guest and greets them with their names and give them personal handshakes!
Oh yeah, Wicked Spoon is the place to EAT!!!!! personal favorite buffet of Las Vegas!
