Hi Jillian:
Montreal is a great city, shopping is to die for. But that said you probably won't be able to get around. It may be a good idea if you can to bring someone with you. I know I was always picking things up for Steph, magazines, snacks and such. We drove back 2.5 hours. Told Steph take the drugs and go to sleep, which she did. Sitting upright in a plane will probably be difficult for any length of time, so taking the drugs and having someone to "watch over you" is a good suggestion. You will need help in carrying the bags as you won't be able to lift for a bit. If you have to bring a campanion, then their expenses can be claimed through a tax deduction as well - at least in Canada. I don't think it will be much different in the US. If someone can't come with you, then it is really a good idea to have someone meet you at the other end when you return to help with the bags and such.
