Last July my husband and I went to Vegas. We said at Aria for 4 night on a MyVegas comp. We are not big gamblers, but I have been getting all sorts of e-mails from M-Life resorts. Including 2 free nights and $30 free play at New York New York. Today I received an e-mail from Aria saying I was Pearl level. Is this the lowest level? I thought it was Sapphire, I know my current card is blue. Could they be confusing me with someone else? Is there any perks for being at the Pearl level?
