Personally I have never been interested in going on a cruise but it was the choice of in laws and I ended up being dragged along. After initially booking Britannia we ended up taking advantage of a cheap upgrade offer to Queens Grill.
It didn't start well at Embarkation when there was a scrum of people surrounding the doors into the hall in Southampton and no indication of where the priority booking queue was. Asking people working their didn't get us anywhere until one guy told us to go straight into the hall which meant forcing our way past the people in the main queue who were rightfully unhappy with us pushing past them where at last we saw the signs for priority booking. Given there are multiple doors into the hall surely it can't be that hard to put signs up outside as well. Though not as bad the disembarkation was also chaotic with little in the way of clear directions.
First impressions of the ship were ok, some of it looked a bit tired but much of it very nice. The cabin was nice and spacious and we were glad to have upgraded.
The Cabin was probably the highlight of the trip sadly. Nice and spacious, well looked after by the butler and generally pleasant to spend time in.
Only real issue was for a taller person such as myself the shower is a bit of a squeeze and the bathroom in general looks tired compared to what you get in good hotels these days.
