Well, I'll be in Scotland next month doing a tour called "Scottish Highlands and the Islands. Starts and ends in Glasgow but goes right up to the Orkney Isles. Fourteen days of kilts, haggis and sporans...lol.
Bugger, you beat me to it - LOL I have travelled on this ship from Southampton/New York/Southampton and we ate in the Britannia Club which is located on either side of the main Britannia Restaurant toward the rear of the ship. A bit quieter and than 1200 strong main restaurant which has two sittings. The Britannia Club allows you to eat at any time between 18:00 and 21:00 and yes there was assigned seating in the Club.
