I live in Atlantic Canada and the weather was beautiful here last week. Cool nights and warm sunny days. September on the East coast is a beatiful time of year.
We did Canada N/E on the Rotterdam this year- Boston to Montreal and paid a higher per diem for an inside than we usually do for a balcony in the Caribbean. It was the most relaxing enjoyable cruise we have taken . Besides, for all who missed Bermuda, you have an excuse to book Bermuda next year now. Go in May and avoid hurricane season.
