I cannot compare this with other parks in Dubai, but we had a lot of fun! The lines start at the ticket booth and continue from ride to ride. I think in 7h we only got 7 rides in (and then 1h for lunch). While the park claims to have over 30 rides, it is actually much less, but i.e. ride #1 is described to combine 11 rides (it has 11 rapids, each has its own name, hence they get to over 30) ... but nothing much to complain about it. This way you only line up once. In the end I would say the most fun ride was the Jumeirah Sceirah (nearly free-fall), but you line up 30 minutes for a 45 second slide. I was positively surprised that the lunch options were not a total rip off (other theme parks take note, I am especially looking at you Disney). The cashless payment system is also nice. They ask you at the entrance how much you want to put on that, before you have any clue how much things are. But worry not, what is left on your wristband can later be refunded.
