My apologies, as I am sure this question has been answered several places before; however, a quick search of the threads didn't pull up any info.

If I want one MyWay Preference at one property one night (i.e. variable miles) and a different preference the next night at a different property (i.e. fixed miles), what is the best way to accomplish this? Through the front desk at check-in?

As always, your insights are greatly appreciated!
