Good Morning David!
I have always enjoyed your posts and wanted to weigh in on the "new Haven" discussion.
I recently canceled a booking I made in the first minute it went on sale for a Haven Penthouse with Master Bedroom and Large Balcony. As more details came out about Prima, the less interested I became. No private covered pool, a disjointed layout and most importantly, not a lot of shade.
The decor is definitely minimalist and comparable to what I've been seeing in renderings for the new Explora 1 - high end, Italian design.
I must disagree with you on your views on the Yacht Club. On Seaside Class ships, I have a private pool, outdoor bar and large deck, albeit with minimal shade.
The indoor lounge is a two story, glassed in affair with the dining room linked to the bar and a wind protected outdoor seating area as well. It is most definitely NOT "just a part of the ship for suite guests to wander about"!
