I actually joined this forum as I'm curious about this...for my last three stays, I'm now 3 for 3 in having to e-mail Marriott to correctly input the points. I'm sorry, but to me, this is RIDICULOUS that I should have to do this. I could see every now and again, but 2009 was also riddled with multiple times where the points were not correctly included. Does Marriott plan on doing anything about this? Quite honestly, this alone is enough to cause me to consider changing to SPG or another (assuming they can get it right!)
