Prices are rising. For some of the more popular events (gymnastics and swimming) tickets are sold out. For others, a ticket can cost up to $3,000 USD (close enough that the difference won't buy a croissant and coffee). Hotels' prices have doubled, tripled and even quintupled their rates. If you are planning to ride your bike, large areas of Paris will be closed to motor vehicles and even the local Metro prices are going up. On the other hand, Break Dancing at the Place de la Concorde and Beach Volleyball at the Eiffel Tower will be free. Bring your binoculars.
