Not a Britannia member but I have booked this evening,
Brochure came through the door this afternoon, could not find the prices on line so thought I would try ringing to ask.
Was told someone would call me back, surprisingly the call came around 7 PM.
For the cruise I wanted standard cabins on E Deck were 25% off but D Deck was 30% off, booked D Deck for less than E deck.
