I went through the link that is in the wiki, and Marriott sent me a phone number to call at the hotel I provided and a link explaining the rewarding events program. Their link says you can earn 10 elite nights if you book 10+ rooms for at least one night. So this requirement contradicts some of the statement made earlier. So I don't see how people are getting 10 elite nights by just renting a meeting room for a hour or so.
