I understand that when booking they tell you to leave an hour or so for travel, but does anyone know how long of a grace period you have for reservations?? I'm attending a tasting with the F&W festival, and am afraid it will run late. Otherwise I only have 5 minutes to get from the F&W Welcome center and Le Cellier. I don't want to lose my table! It's the first time in YEARS that I've even been able to get a spot.
