Going back 'home' with older kids

[Todayissunny]

3 DSs 15, 15 and 17. I haven't been back to the uk since sept 2019, and the kids even longer. We are now thinking about going over the easter holiday for about 10 days. It was easy when they were small. But I just don't know how we would fill our time now. What do you do when you go to visit with your older kids?
Ive got a lot if family but we haven't got a family home to go to. DM lives in a tiny place alone, no room for us.
We would meet up with family, probably for dinner or a walk on the beach. But what would you do and where would you go with 3 boy teens? one walk on the beach would be their limit. They are very active on holiday(skiing, wind surfing, diving) or at home hanging around with friends or playing computer games.

Family are norfolk based.

Rent a forest holiday lodge or similar close to were you want to be, you can then visit people, they can visit you etc.
My kids were always fine doing this, they had ipads, enjoyed various activities onsite, often there's a go ape or something nearby

I found this stage the most exhausting and expensive tbh and was almost glad when Covid intervened and made us stay put for two successive summers. They did surfing ( brrr), outdoor activity camps, trampolining, dry ski slope, roller skating.. We have a huge family but little by little the cousins grew up too. And we were always cluttering up someone’s spare room whereas at home we have a pool and all their friends are here but they were always desperate to go back.
Fortunately one is now at Uni there and the other is following in September so after many a long summer, i’m Off the hook!
