As a travel guru, I'm obsessed with racking up points and miles. I did a destination wedding in Ireland, and fabulous though it was, I'm bummed that I missed this awesome opportunity. Have your wedding at one of 42 Marriott, Renaissance, or JW Marriott properties, in all sorts of fabulous locations (Hawaii! California! Costa Rica!) and you'll earn 150,000 Marriott Rewards points—that's good for a six-night stay. There is a catch. You have to spend a minimum of $25,000 on catering, if your wedding is held on a Friday-Saturday. But think of the cash you'll save on the honeymoon hotel.
