The lifts on the Balmoral are quite inadequate for the size of the vessell, but there are two sets of two and the forward lifts do go to deck 11. There is no walkway as such, just steps as an alternative. It's actually a splendid lounge area when you get there, with great views over the sea, and a bar with bery friendly staff.
Thank you, as there does not appear to be any lifts to deck 11 on the deck plans I contacted Fred Olsen and they said that the lifts only go as far as deck 10 and therefore the only access to deck 11 is via the staircase!! I thought this strange as they claim to serve food on deck 11 when the weather is good.
