is five weeks in greece with kids too much?

We’re about to spend five whole weeks in Greece with our two kids (5 and 10) and their grandparents. My husband’s joining for part of it, but most of the time, it’s just me wrangling the kids and keeping everyone happy. We’ve already locked in a 10-day cruise and two weeks split between Athens and Crete. That leaves us with another two weeks to fill, and honestly, I’m torn. I thought about just relaxing on islands like Naxos, Paros, or Kos, but I keep picturing the kids getting bored after the third beach day, and me scrambling to find something new to keep them entertained. Plus, I know the grandparents aren’t up for anything too wild, but I don’t want us all stuck in a rut, either. We’ve already done Spain, Italy, Turkey, and most of Western Europe, so I’m itching for something different, but still easy enough for the whole family. Has anyone else tried to balance kid-friendly adventures with downtime for the older folks? I feel like five weeks is a dream, but also a recipe for a meltdown if I don’t plan it right. It’s like, how do you keep everyone happy without losing your mind? #familytravel #greece #travelwithkids #Travel
