I got the same email to. I'm wondering if it's going to match their summer promotion where you could get up to 10,000 bonus points starting with your second stay. The whole Marriott summer bonus thing was a little bit confusing because when it said that you got 2000 bonus points starting with your second stay I wasn't clear if that meant each time or starting with the second stay at self but it looks like it was for every stay after registering for the promotion following just one total stay.
