A little more specific, with quotes from one and others…
It’s a personal choice, for us (now always) Club is worth the small additional, as it’s not much more than a B grade balcony. Service in Britannia Club is exceptional and one has the same a table (monopoly) with only one sitting (freedom style-take as long as one wishes) for Breakfast, Lunch and Dinner. Expanded menus (flambé), a proper cheese trolley (served) not pre plated. And so on….

These are the same reasons we only book Club all the time since being on the QM2. The Dining Room same table and timing was the key factor on our decision. The Extended Menu which is Pre Grill Experience gives us the taste of the next Classes. Not to mention the Flambes and dishes prepared at the table by an Excellent Maitre de.

The service, as others have mentioned, is impeccable and we never struggled to choose. The extra a la carte options helped with this. The flambé is particularly special.

We agree it's worth it with a possibility of a Upgrade if possible.
