As with any time you are comparing loyalty programs, a bit of common sense has to apply:
- Which properties are more convenient (location and/or price) for your staying patterns?
- What awards to you aspire to?
- What elite benefits are more important to you?
Sure, you can get HH Diamond with just 28 stays (which sounds pretty easy with your travel patterns), but you can work the MR system with the MR Premier Visa and rollover to make Platinum with many fewer actual butt-in-bed nights than technically required.
What have _your_ experiences been with both programs that would make you stay with one over the other?
