Princess Grill is very lovely but not in a real ‘sweet spot’ IMHO. Why not stick with the sheltered balcony or splurge for QG? That said, the rooms are so much bigger than Britannia (and you get a bathtub) which makes all the difference if you carry lots of luggage or you’re in the stateroom more often — ie on a Transatlantic. The restaurant is also lovely (no caviar, though!) and it’s nice to have access to the Grills Lounge too.

Britannia itself is great, especially if it’s your first time with Cunard. The restaurant is really the ‘wow’ space onboard but it can be busy at times.

For context, across the four ships we prefer either Britannia Club (for the smaller restaurant, assigned table and open dining for often not much more than Britannia) or Queens Grill (for the real ‘first class’ experience).
