We couldn't fault the itinerary - Copenhagen, Stockholm, Helsinki, St. Petersburg, Taillin and Zeebrugge - all well worth visiting. Our only organised tours were in St. Petersburg, preferring to make our own discoveries in our own time, but recognising that the Russian visa system is sufficiently daunting to be best left as someone else's responsibility. The cabin was as roomy and comfortable as you'd expect of a "Standard Inside", and was kept consistently clean and tidy for us.
Most of the staff were excellent - Entertainment staff particularly so. The glaring exceptions were at the Reception Desk, unfortunately, ranging from vague and unhelpful to argumentative and rude.
Can we justify Cunard's 6 star rating? I'm not so sure. The Old Queen is nicely fitted out, to be sure, but not twice as good as the 3-star Pacific Dawn, for example. The food and wine in the Britannia Dining Room were excellent and well worth their rating, but the Lido Buffet, while perfectly acceptable, simply wasn't notably better than less lauded competition.
