That's a good point, Mike. It's like driving through Big Sur; going north is preferable.
Charm, I've looked at the accomodation page, it's very helpful. I was looking for opinions. The hostel in Wentworth looks like a possibility.
GuyO,
ferries.ca says that the rounnd-trip fare from NS is $70 and that you can't get a one-way fare in that direction. However,
confederationbridge.com says that if you take the ferry over and the bridge back, you pay only the bridge toll of $45.50 for the round trip. It sounds like what you're saying, but it doesn't make sense to me.
