We had really nice half board family holiday in Tres Vidas. The place is clearly targeted for families with children and I wouldn't recommend this place if you area looking for peacefulness.
While we had a great time, there were few things (see below) which prevented us for giving a full 5* rating.
While all-inclusive food selection was versatile and plentiful, main courses at the dinner were missing taste. Breakfast was everything you could expect.
We were super-lucky with the heat wave (26-27 celsius) and could all enjoy of the pools, but only one of the pools was actually heated. When its gets any "colder", the wind and cold water will pretty much keep you off of the other pools, incl. children's pool.
Children enjoyed the Bamse Club and swimming school. For adults, there is a quiet separate SPA with two saunas and warm pools (cost 10-14€ each for 2 hours). Gym was quite basic, but free.More
