Can those of you more experienced shed light on these mystery bonus nights? I know we get a bonus 15 elite nights after spending a certain amount of money on the SPG Amex now but can you combine it with the Ritz Carlton Rewards to get 30 elite nights. I saw somewhere Marriott used to issue 1 elite night per $3,000 spend? Is that unlimited and still ongoing? Does anyone know if you can get all 3 cards and combine the elite status? I'm not a business traveler but rack up a lot of credit card spend and would like to maximize upgrades through status if possible. Thanks for the input!
