Hey BritChris - You are welcome, doing the tour takes away your freedom to go where you want and when but it also takes away all the stress of driving in a stange city/area. My hubby loves the challenge of the driving but if it were me doing the driving, I'd be on the tour. Hope you get great weather and enjoy my province and country.
Billybuzzy - Have you thought about doing the Fundy Park/the Rocks tour instead of a repeat to St. Martins? If you are afraid you may not get to O'Leary's, you could always grab a case of Moosehead and have a few on the bus. Have fun!
