Trying to decide whether to buy chips or not to gain access to the 2 night rewards and the 4th reward. However, since I only have 630K, it would help to know what the current LP required for the hotels I am considering. Could someone tell me what I would need for Aria, Mirage, MGM and MB? Also, what are the $100 free plays running for? Are the prices fixed or do they fluctuate depending on level and VIP status? Can it be one $50+ purchase? I read in a post on FB that it can't be one purchase. True? Appreciate any and all info. Thanks.
