A place worth spending at least one day and preferably two. I suggest choosing different dates than holidays because it is supposed to queue for 1.5 hours. I was in March, the weather came ok, and for one rollercoaster queue I waited 30 min. It's a good idea to familiarize yourself with the plan and set compulsory places and start from them because the queues are smaller in the morning.
