A huge thank you to everyone that has contributed to this thread, especially the wonderful contributions of @Sthrngary, I have learned so much from this thread. We are on our first day of Breakaway haven today. If anyone has any questions let me know.
Pre-cruise concierge was a bust - none of our requests were actioned on the ship.
FYI American Diner is no longer available to haven on embarkation day on the breakaway.
Everything else has been fabulous, haven restaurant, butler, steward, bar staff, all wonderful.
