DH and I are American expats living in the UK with our DCs ages 7, 6, and almost 4. We're looking to go somewhere in Europe for up to 8-9 days this summer. Like most young kids, our DCs don't fancy museums, historical sites, nice restaurants basically everything that would make you want to go somewhere. They are active kids and won't be happy staying home all day, even if "home" is a lovely villa with a pool. So we need convenient access to a beach, lake, or similar outdoor place, and fairly reliable weather. DH and I would like to feel like we're really "away," so we don't want to go to a big resort-type thing, but beyond that we're resigned to having a kid-friendly trip. At the same time we'd love to avoid huge crowds, if that's even possible in mid-summer. Villa, hotel , or flat is fine as long as we don't have to all sleep in the same room.
I won't say money is no object but the budget is generous. We don't get to do trips like this often and we are looking for luxury accommodations.
We've narrowed it down to Italy (probably Puglia), Croatia, or somewhere in the Alps (not much narrowing I know!), although we'd be open to other fantastic suggestions that meet our criteria. Which would be best for us? Thank you so much for any advice!
