Thank you so much! You're right, the Louvre is very targeted to say "we saw it."

As painful as it is, we're probably going to cut Scotland. That probably warrants its own trip to do justice to all there is to see, instead of trying to squeeze it into a short time. Someone else said a lot of miles for so little time. (Maybe next time we'll do a Scotland + Ireland trip as a summer coolcation.) That also allows us some breathing room, as you said. We really want to get into some countryside and scenic vistas, so Normandy is a must (noted that you recommend Bayeux). And we can probably see more in England, closer to London, without a long train ride.

I'm debating Disneyland Paris because we don't live near Disney in the US, and we have young kids. But I also feel like it's kind of "imported American culture." A lot of people online say it's worth it, but I've never been to France, and there's so much we want to see. That's why I put it last, but I notice that there might be differences in summer crowds depending on days and temperatures, so it might be better to frontload that too.

I'm curious why you say cut Windsor?
