I get a family season pass at Seymour. The great thing about Seymour vs Grouse is that you can walk to and from your vehicle any time (no gondola). Spare clothes, lunch, second board, tools, etc are all available.
And while Grouse and Seymour family passes are reasonably close in price (although the scheduling's different for buying them) the pricing at Cypress is ludicrous. They aren't *that* much better!
