Monaco Grand Prix
Concierge.com's insider take:
The madly popular European sport of Formula One (or just F1) racing comes to Monaco just once a yearand it is an event. Held on a Sunday toward the end of May, the race often overlaps with the Cannes Film Festival down the coast, providing a double dose of glamour with two different demographics (think sports fans and lizard-skinned yacht owners vs. Hollywood celebrities, paparazzi, and, well, lizard-skinned yacht owners). The city is closed off as massively overpowered open-wheel cars scream around its tight bends, up and down its hills, and past the port, all to a packed crowd. Don't count on getting a room in town without reserving months, or even years, in advance; the same goes for staking a claim to a table at the more glamorous restaurants like Le Louis XV.
