Looking for inspiration!
We have two DCs, will be 12 and 14. More into adventure and active stuff than many teens (will not be going off to make new friends, will be asking where the swimming pool is).
We don't really like lying around on a beach either. I can't really climb big hills but city walking is fine.
Last few years we have done Dorset (cottage), Northern France (coast/Disney) and also a trip to the US that was interrupted by illness (don't really want to repeat that though).
