Hi Al, Sorry for not replying sooner, but I've been disconected with a recent death in the familly.
I work close to old Montreal. My word of advice, once in the city leave the car at the hotel. the constructions is terrible, lots of detours, plus if you intend on visting Old montreal walking makes a lot more sense... Lots of museums, great restaurants and very pedestrian friendly, plus the weather this year is simply incredible, hot and sunny. Language wont be an issue as the city is mostly bilingual..plus old montreal being a tourist area makes it more English than some other part of the Island ;-)
Cheers
Fred
