We actually are planning to go to Montreal instead tooIt depends on how much you want to risk your application for the trip.
We applied inland and actually had our honeymoon in Canada because we didn't want to risk crossing the border.
He is from a visa exempt country and theoretically should be OK to cross the border. But again, we didn't want to take any risk.
I am happy with what we did. Montreal was beautiful and food there was great.
We decided not to risk it. We'd rather get everything sorted out, and go on that trip after he gets approved.
