Aqualand is a lot of fun and quite easy to get too. You could always book it at one of the travel places or somthing like that seen as there are usualy alot of people that want to go aswell.
There is lots to do there, Big slides, Fast slides, multiple people slides, lazy river, wave pool, raft rides and etc.
There are also different pools and they have fun pools like pirates and stuff.
But if your not fond of rides then you can always just sunbathe and they have plenty of food stalls which can be a rip off but its how they make there money i suppose.
