Returned from 14 nights aboard Britannia West Med
Embarkation ( 1 hr ) and Disembarkation ( 2hr ) went as well as one can expect and considering 3000 people to sort time on Disembarkation was more due to the fact you asked to leave room at 8am and waited till 09.15am at an area on ship till given instructions to leave.
Rooms vary on board depending what your requirements are. We opted for a superior room on A deck, port side, mid forward ( deck 15 on map of ship )
Port is what it is really
