Wow thank you to everyone for your input thus far! I really appreciate the diversity of perspectives (which confirms my initial thought that there are several competing priorities to weigh as we decide).
I also appreciate the words of wisdom that fall into the “other things to consider” category, which are very valuable to me. Thank you especially for the refrigeration tip and caution re: traveling through European security with items than cannot go through the x-ray machines-that is definitely something to research heavily before our trip!
To address some of the comments above, in no particular order:
1. We have all lived in Florida all of our lives, so the heat may not be as much of an issue for us. Yes, it’s unpleasant, but if we can survive 12 hours at the Magic Kingdom in August, we can probably tour Europe in the summer.
2. Notwithstanding #1, I won’t plan to tour 10 hours a day every day! I personally would be a “Cathedrals, Castles, Forts and Ruins” guy as referenced above, but my wife and kids can only handle so much of that. That’s why mixing up the touring and relaxing works best (even if I push them to tour more in Europe). They’re always up for an adventure and truly enjoy it, but they need downtime more than I do.
3. I’ve considered (and am still considering) pushing Europe off until kids are in high school. And we may. On the other hand, we only live once and truthfully I’d like to do all three itineraries if possible. So maybe start earlier?!?
4. I’m glad to read from many that the language barrier is not as much of a concern. I’m still trepidatious though, as when I am speaking with people who speak only English, they sometimes have trouble understanding words like “gluten”, “wheat”, “Celiac” and “cross-contamination”. I’ve read that places in Europe tend to be better with accommodating Celiac diets, but we virtually never eat at restaurants in the US because of the risk. This also will be heavily researched.
5. We all love pools and hot tubs and the top deck (and Boardwalk and Central Park!) I’m disappointed that Anthem is not staying in Southampton, as it would be much easier to justify the colder trip on a ship designed for it. If it’s cold and we are trapped inside without much to do, that wouldn’t be ideal.
I appreciate the discussion and thoughts and hope this topic helps others! Thanks everyone!
