My wife and I ( mid sixties ) have been to Gran Canaria for the past six years late January or early February. We go to Clubhotel Riu Gran Canaria, which is situated on the sea front in a lovely small resort called Melonaras.
It is a " all inclusive " hotel and has evening entertainment.
We really look forward to our visits here every year.
You can book through Thomsons, or book direct with the hotel.
I would advise you to read the reviews on Tripadvisor, or Thomsons, just to make sure it meets your requirements.
Hope this helps.
