Premium: Paying $10+ for a drink at a casino bar, and $20 in a club. Probably $10 inside IPL4 but we'll see.
Perk: smoking indoors everywhere. (Most likely not inside IPL4)
Premium: Expect to pay $10 for a pack inside the resort.
Perk: Girls go clubbing for free (for the most part)
Premium: Guys pay $30-50 and may or may not get in depending on the "chicks to dicks" ratio of the party. Chuckie plays tonight at Marquee and Markus Schulz spins on Saturday. I will buy tickets at the concierge and forgo the lines. Don't forget black shoes or you won't get in. No sneakers.
Perk: A vast resort to explore. I think the pool will be open as well. Many attractive and well-dressed people.
Premium: Don't be surprised when you see a mysterious $15-25 "resort fee" charged to your credit card.
Perk: The Terrace Studio room in the Cosmopolitan will have a microwave.
Premium: Most likely, there will only be a mini-bar refrigerator that automatically charges you should any item be removed. Food inside the resort will be expensive. One should strategically plan their meals if they wish to save money.
Perk: Free parking at any resort. Lots of entertainment within walking distance.
Premium: A cab ride to the other side of the strip will be expensive (but worth it over a DUI) due to traffic. Do not valet park your car.
Perk: People in Las Vegas are very friendly. Guests for the most part are there to have fun and relax and very willing to strike up a conversation. Service is excellent. Maybe even Japan-quality service.
Premium: There's a charge for good service. Expect a whopping five dollar ATM charge. Also, expect to encounter the usual drunk asshole here and there.
