I'm not as optimistic as others are. 9:05 is not the time you would be riding Soarn'. It's the time you are allowed in the entrance. You then have the long walk up the ramp, you may or may not be stopped at the FP reading spot, then the seat assignment spot, then the safety film, then loading and 'preflight' checks all before the ride starts. You'll be fortunate if the ride starts before 9:15.
The ride is 4 min 51 seconds. So now it's 9:20 and you aren't out of your searts. You wouldn't get out of the Land until past 9:25 so you would be late. And that assumes that everything works out perfectly at every spot where a delay could occur. In reality, your best case scenario is arriving at Akershus closer to 9:45 (or later) than 9:30.
