Unfortunately, the cheese weigh station in Edam was closed at the time of year we attended (October). Made that part of the tour somewhat pointless - this should have been noted on the tour info.
Be advised - it's a solid 2-3 hours each way to Bruges from Amsterdam (without traffic delay). While Bruges is certainly worth visiting, it makes for a long day. If you're surrounded by loudmouths seated around you (one woman didn't shut up throughout the whole 3 hour bus ride), it's pretty painful.
