We may be traveling via ferry from Vancover to Swartz Bay on Labor Day. Would you recommend that we make reservations or will we be OK to just show up at the ferry and try to get on. We will have a car that we need to transport. Because we are flying standby into Vancouver, we don't know when exactly we will get in, so reservations may be hard to keep. But we also don't want to waste time in trying to get on if it's a hopeless cause. Any help would be greatly appreciated. Thanks!
