Ooh Ferrari World,
Went there during Eid.
The simulators are excellent and if you go there early then you can comfortably get on them.
The rest of the rides are pretty much exhibition rides really, nothing too strenuous but the Formula Rossa (worlds fastest rollercoaster) is the craziest ride I've ever been on.
I've been on some awesome rides but the Formula Rossa is easily the best and physically an experience worth doing. (not for the faint hearted. Also I'm 6'4 and barely managed to fit, if you're taller than me, or for example someone who is overweight, then you may well be turned away. (I almost got turned away because my height was an obstacle and had to contort myself slightly for the safety bar to engage properly).
It gets busy in the evening to go for midday and you'll be fine.
Finally, if you can afford it, get the VIP tickets. The park looked pretty empty but the queues are frustratingly long and when you wait an hour for a minor ride, and it's not even that good, you're better off with VIP so you can try everything, and at worst go on Formula Rossa a couple of times.
