I am cruising out of NY in Sept and I am very excited, I am however going south on my cruise.
As for the cruise to Canada, I am sure the time of year you would be going will be Beautiful.
I live just outside of Saint John NB and I agree with Lisa, the Reversing Falls ride would be a lot of fun.
Now that I am noticing the cruise ships, and am excited to go on my own cruise in the fall. I plan to drive in to Saint John this summer and be there to watch the cruise ships come into port, perhaps I will see you in Saint John LOL among the thousands
