"New" Promenade Inside Cabins on ISLAND Princess

This question is about PR707 thru PR725 which are 8 Inside cabins aft on Promenade Deck - part of the Island remodeling project I believe.

These look like they may be "sideways" oriented staterooms that are found on Riviera Deck of Crown/Emerald/Ruby/Caribbean and also in many locations on Royal/Regal.

Can anyone tell me if those cabins are indeed "sideways" or if any others on Island are (I don't think any others can be).

We had a sideways once on Regal and liked the layout.

Thanks.

I believe the cabins I referenced are indeed "sideways" oriented based on inquiry to 800-PRINCES(S) today and the agent running it up the ladder.

But would still love to hear any first-hand experience.
