Island Princess - Interconnecting Balconies E Deck Aft?

[CaptainPedantic]

Looking for some advice on the Island Princess balconies on E deck aft please.

The Princess deck plans have special notes against these cabins - e.g. for cabin E706 "Special Notes:  Balc Cannot Connect With E704 Balcony".

When looking at exterior images of Island (like the one here), it looks like this is because these balcony cabins are separated by steel walls BUT it also looks like there are adjacent balconies that could have the divider opened up... So E706 could connect with E708 as they are within the same part of the steel structure, but not E704 as it is separated by a steel wall... 

We're looking for 2 adjacent balconies where we can open up the divider, but don't necessarily need interconnecting cabins on the inside... 

Could anyone confirm that these cabins can indeed have their balconies connected? And any other advice on Island Princess balconies is appreciated... Many thanks in advance!

We ended up asking our TA about this, who in turn asked Princess for confirmation of specific E deck aft balconies that could be opened up. We were offered E631 and E633 which is as I expected - E631 has special notes that it cannot connect with E629, which infers E633 is ok... We're booked now so let's see - I'll report back once we're home in case anyone else is interested.
