Epernay, the true capital of the champagne region is only a few miles further on, and they have a free Motorhome Park, with services, not far from the centre. From there it is a stroll to the Rue du Champagne, to try a few samples!! The town centre is also not a long walk away, with several excellent pavement restaurants to choose from.
Rue Dom Perignon in Epernay can be a bit noisy in the morning as school buses are parked adjacent but echo what JFD says. Will be there for 36hr from Sunday. You can book your English language tour with Moët in advance as they are a bit restricted out of season.
