Hey ssschmokin1,
If you got into Scandinavian Aviation Academy's Ryanair Type Rating Course you will need to stay near SAS Flight Academy because that is where it is taught. SAS Flight Academy is just outside Arlanda Airport (ESSA) and they have their own student accomodations called Night Stop. Check out there website at
http://www.sasflightacademy.com/ for more info. I am kinda suprised that they didn't tell you this. Welcome to Ryanair!!
Best of luck,
GC
