We had a wonderful time at the Ventus at Marina El Cid & Spa. The resort was beautiful, staff was very friendly, restaurants served high quality food with lots of options, and service was incredible. There were lots of activities for the kids and the pools provided lots of fun for them too - foam party, waterslides, cliff jumping, volleyball, polo, and water games everyday.
The only drawback to this resort is the beach. It is very narrow, has big sandbags blocking the swimming area, and it had a lot of green seafood washing up on it. We did not use it alt all.
If the beach is not a huge priority, I would highly recommend this resort.
