Be extremely cautious of the free shuttle service ...

Be extremely cautious of the free shuttle service from Dubai to Ferrari world and back to Dubai. If you are not very careful, this could cause a complete nightmare like it did for me.
A morning delay caused me to arrive 2 hours late. I was told by the information desk at Ferrari world that the shuttle back to Dubai was leaving at 7:30 in the evening, which was not the case. It had apparently left at 7:00. The lesson here is if you use this shuttle service make sure to check online constantly because I was told it could change at any time and could even change daily. Make sure you are in the correct location in Dubai because I was told those have changed also, again check online for the most recent. For your return back to Dubai, I would recommend being there at least 30 minutes or an hour early. There is WiFi you can use during your wait. If they say the shuttle leaves at 7:30 in the evening, make sure you are there BEFORE 7:00 just in case.
Formula Rossa (The Worlds Fastest Coaster) was great but Ferrari World has a lot of room for improvement. I am writing this review to hopefully prevent someone from going through what I had to go through using the shuttle service.
