The French Open tennis tournament, officially known as Roland Garros, kicked off Sunday in Paris. Hardly a cheapo event, but tennis fan Cheapos can get the “Evening Visitor” passes at 10 euros for play after 5 p.m. on certain courts. Availability is based on the number of seats vacated by people who have already left the stadium for good. On a clear day, you can often expect play up until 9 p.m. The offer is good for the first week of the tournament through Sunday June 3 inclusive. The “Evening Visitor” passes will be available at the ticket windows at the Porte des Mousquetaires for those outside the stadium. To get to Roland Garros, take the metro line 10 and get off at Porte D’Auteuil.
