I don't have any knowledge on that particular cruise, but just curious, I didn't know whether you all have been on a cruise before? If not, a 21 day cruise seems kind of long to me, in case you don't like it. And those are all relatively small vessels. Not a huge amount to do on the ocean crossing, and I would do some checking about how rough to expect the ocean to be on that crossing. With regard to ATLANTIC crossings, I know that the time of year also figures in a great deal, as to how rough it can be. Glacier Bay is magnificent and Vancouver is a beautiful city. The rest of the ports I have no knowledge of at all. If you do decide to book the cruise, PLEASE do it through a travel agent and not directly with the cruise line.
