Los Alcazares is definately a place for older couples or people who want a quiet relaxing time.
We loved it but our teenage children found there was nt enough going on for them We stayed at an apartment block called Albatros very nice but the pool was too small for the complex and the behaviour of some of the people in the pool was boardering on dangerous. We would go again but to a more relaxing complex and let the kids go to Benidorm The Mar Menor is lovely. Boat rides are good. One or two nice restaurants on the beach.
