I have some questions about the mlife tier system. Do you get 25 tier credits for every dollar you spend while shopping at The Crystals and is there a limit to how many points you can get this way? Can I spend $10,000 and become a platinum tier member instantly? Does the Venetian or Caesar's Palace have a player's club system and can you earn tier points by shopping with them too? I enjoy dining, shows and shopping, so the better the tier, the better it is for getting more of what I want out of Vegas. Are you more likely to get a room upgrade or a comp if you are at least a platinum member? Would I be more likely to get them if I went shopping first, hit platinum and then checked into a hotel or would it be better to book in advance? How can I maximize tier credits earned when planning a trip? Is there a confirmed way to get a NOIR invitation? If I don't gamble would I be less likely to get a NOIR invite even if I got millions of points spending money in other ways? I read you needed 2 million points before they made it invitation only.
