Hi there, we have been on Britannia several times and have always loved the experience, the food is varied, tasy and plentiful, the entertainment always great, the decor really has some highlights. Which reviews are you reading, and what in particular are your concerns. If you post them I'll give an honest opinion.
I'll also try & find our review that we wrote after our first experience on board.
