The second biggest hotel in Las Vegas (and in the world) is the MGM Grand and with everyone trying to stay solvent and save money, they are doing their best to fill their rooms, restaurants, and shops with clients so that the people who work in those places keep their jobs.
It is now easier than ever to be treated like a whale (high roller) without having to spend thousands at the tables. The MGM now has a program called Prima that gives you VIP check-in, upgrade to a celebrity spa or bungalow suite (or a $50 credit if you want a regular room), roundtrip limo to another MGM property, a one level upgrade to tickets at Cirque's KA, VIP entry and escort into both Studio 54 and Tabu nightclubs, 2 for 1 drinks at the lounges, free access to Wet Republic pool, free access to the spa and fitness center, 2 for 1 entrees at 8 of the fine dining restaurants, (including L'Atelier, Seablue and Craftsteak), complimentary bottle of champagne when 2 people dine (at $89 per person) at Joel Robuchon, MGM Buffet VIP line pass, and a no wait taxi line pass (which can save you an hour during peak times).
What do you have to do for all this? Spend at least $500 on your Prima account (aside from your room charge). All the fine print is here, but after reading it, I still found everything was straightforward, without any hidden surprises. It's easy to spend $500 in just two days with two people in Las Vegas, so why not do it in a place that will give you perks you really can't pay for, like VIP line passes, in addition to saving you money on food and drinks?
Laissez les bons temps roulez as a high roller in Las Vegas!
