You will have to post a Google Map of these locations. It's quite fun to let your travels be dictated by the weather.
Me: I would probably return the rental car, jump on a fast TGV (overnight?) train to Paris, and get a ticket to the French Open (Quarters?).
It's a bucket list item to see some Grand Slam tennis in person, especially Wimbledon. However, the reality is: watching top players on small courts at Masters 1000 events (Indian Wells (Palm Springs, CA) and Miami --> Sunshine Slams) in the rounds of 64 or 32 is the real treat (one can sit behind the umpires and hear/see everything) - Not sitting in the nose-bleed seats at a place like Arthur Ashe Stadium/US Open.
