It shows I'm registered for both the points and miles megabonus - so if I switch my earnings preferences can I get both bonuses in the same period. Basically, I've already done a few mileage stays -- but I have a few more expensive stays coming up so I want to switch to points now. Will I still be eligible for the points promotion for every other stay?

Also -- how quick / often can I update this? If I made a reservation when my earnings preference was miles - can I switch to points after the fact, is the system quick enough to do this on a daily basis or when does it "read" the info. In an extreme scenario, if I had consecutive stays switching between points and miles and back to back nights - what time/when would I want to have changed my preferences by?

Thanks!

I am doing the same thing, because my Megabonus only counts for stays including a Thursday night, but my Megamiles counts all stays. I collect miles until the stay ending Wednesday night posts to my account, then switch to points. Once the Thursday night stay posts, I switch back. It has worked perfectly so far, but any unusual delay in posting the Wednesday night stay could ruin my process if the Thursday night stay posts before I can switch back to points.
