Prinsendam question

On the Prinsendam, cabins 030 to 037 are category SY and there are blocks of SS cabins both forward and aft of this SY block. Does anyone know why they are a lesser caregory? There doesn't appear to be noisy venues below or above. They are near the elevators, but it appears there are some SS just as near. if elevators are the answer, just how much of an issue are they? thanx

In a deck plan from 2011, before a fleet-wide re-categorization took place, everything from 022 to 037 was SY, so the question is why did 022 to 029 become SS? One possibility, if this diagram is correct, is that they have larger balconies.

We have travelled in 036 and in 039, the elevators were not a problem, their proximity was very convenient. The bathroom in 039 was different to 036, no bath, instead a roll in shower with seat, as 039 is a disabled suite.

Have no idea why the classifications are different.
