My parents suggested a river cruise, even though they did one before and they said the evenings were boring - no entertainment like what you find on the mega ships. I looked into it watching a youtube video of it and I've come to a conclusion that neither my husband and I who are active and like to do a lot (even in the evening) don't want to be stuck on a (what I call) a Snooze Cruise LOL!! Basically, in the evenings there is nothing to do.
We are considering a land travel so we can also tour Germany and France. However, not 100% bought on the idea as we are big cruisers and love the idea of unpacking once and seeing many countries.
The Norwegian route is a consideration, but since we live near the Canadian Rockies and when we saw Alaska, we didn't think it was anything special as it's very similar to home, we were wondering would we feel this way about Norway, Sweden, etc.?
I saw a Spain, Portugal and France cruise. Maybe we'll do that.
