I’ll answer my own question as am now on POA. It was worth it. As promised by NCL rep, reservations would be plentiful for suite passengers once on board. All requested times were available. Concierge did advise booking with rep available in Cagney’s for embarkation lunch.
and yes ship was sold out.
In other news, all venues are now open including Key West Grill. Staffing seems fine, service excellent and recent redo of interiors makes ship feel much newer and nicer than when aboard eight years ago.
