I'm the week later...I did the Canada thing last year...not a bad itenerary but I reeeeallly want an enviable golden hue to come back with. So, I've been going tanning to supplement myself in case of a change in plans. Ha!
I doubt you'll have problems. I just got back from my cruise on the Legend from Sept 4-12th, PR, St Thomas and Tortola. I was sad to leave the ship! The crew and staff was sooo accomodating. We had two medical emergencies while in transit to Puerto Rico and one when we were on our way back to NYC. The passengers had to transported by the coast guard. Amazingly, we made perfect time. The captain and crew director will keep you updated about the hurricane...if there is anything they are worried about they will let u know. We went to Puerto Rico when the storm was 400 miles away.. however we weren't nervous at all as we were well informed at all times.
