The personnel, the proximity to the Aquashow park, the room with view to the swimming pool. You need a car in order to visit around and go to the beaches.
I recommend tourists (up to 3) to take the airport shuttles which are very reliable and about which curiously, the hotel personnel doesn't say a word (they recommend taxi which is 35€ while the... hva folk sier » bus is around 11€/pers) -
the indoor pool great for kids, nice jacuzzi, and two outdoor pools great for kids and adults.
Nice rooms with different bathrooms within the theme of water. Nice Gim.
The biggest advantage is undoubtedly the integration with the water park, which is a few meters.
