Road trip! where to visit en-route to Holland?

[callmedave]

I will be a passenger on a weekend trip to Holland in early August, but due to ferry crossing times etc we are not in a rush, does any know anywhere good to stop for brunch/lunch on the way through? any Car museums/attractions worth visiting?

The route is not strictly planned so gives us options.

Which ferry terminal are you arriving at?

Where are you looking to end up in Holland?

Brugges, Ghent and Antwerp are pretty nice, especially Antwerp, the rest of Belgium is not really worth stopping for.
