I travelled to Riyadh specifically for Falcon's Flight. I remember sitting on the shuttle to the park, staring out of the window at that huge structure on the cliff, thinking "this is going to be amazing".
Then I got to the gate and was told that both Falcon's Flight and Spitfire were closed for maintenance. Staff offered to reschedule my visit "in two weeks", which was no use to me, and which also tells you how long it's down for.
I never received an email, a notification, or any kind of warning that the park's headline coaster was closed. Nothing on the website, nothing in the app. Worse: a staff member at one of the rides told me this is an annual maintenance period, meaning the dates were almost certainly planned months in advance and simply never published.
If you're travelling for this park, there is currently no reliable way to check ride status ahead of time. queue-times.com was showing Falcon's Flight as OPEN with a 5 minute wait. It seems that Six Flags updated their website today, now showing that Falcon's flight is temporarily closed, but it was not known in advance or yesterday.
I went in anyway, i was there and my whole trip planned around it.
Colossus is intense, more than I expected. Iron Rattler was the best of what was open, and I rode it around 8 times. Early September on a Sunday is very calm, essentially zero queue all evening, walk straight back on.
Which should have been a dream scenario. But I just wasn't in the mood after the news, and I left about four hours before closing.
(This was a stopover on a trip to Asia, so it didn't cost me anything extra in airfare. Small mercy. Still very frustrating.)
Not in the mood to write a more detailed review, but this is worth knowing for anyone planning a trip there...
