2. Chelsea Clinton & Marc Mezvinsky

This former “first-daughter” got married in 2011 to the tune of around $5 million. One thing I find really interesting is that they rented some air-conditioned tents. I'd never heard of that before, but it's a great idea; I don't know about New York, but it's hot enough here in Georgia in July that I'd see a $600,000 air-conditioned tent (see: today.com) as a blessing! Okay, maybe not that expensive, but you get the point. At least it's useful, unlike some things...
