I think Vancouver could re-use much of what we built originally to host the winter Olympics+it was a huge boost to our tourism sector & economy in general. The Olympics upgraded us internationally from a tier 2 to a tier 1 city. We'd definitely need to free up a bunch of hotel space for it though.
Overall I'd say Vancouver came out the better for the last Olympics and the hefty injections of cash we received helped build some much needed infrastructure. Rinse and repeat?
