Being given a pager on Ar
After being given a pager on Arvia we were advised to wait in Andersons Bar as that was basically the range of the pager, so not actually standing in a queue!
I have been on Iona, and didn't have any problems with the app. Although as there were three of us, in two cabins we didn't use if for booking meals. We didn't have any problems as walk-ins either, but so saying that the ship was only sailing with about 50% occupancy.
Having sailed on both Arvia and Iona, I tend to think that the main problem is the lack of main dining rooms. The 6th Street Diner and The Olive Grove, which replace two of the dining rooms on Iona, don't seem to have the seating same compacity. I am sure someone will correct me if I am wrong!
