There is a 1-2 foot width difference between S107 and S 108. S107 being wider. This difference is enough to have the beds position differently. S107 faces from of ship, S108 is orthogonal to front.
We were in S107 on Discovery for 7day Alaska Cruise. Quietest Cabin I have ever been in (30 cruises in various cabin types and locations). Area is very private, pool/bar area is close.
