1. The actual restaurant is a mirror image of the PG, but actually has a few more tables and seems more crowded. This leads to being quite close to the next table, which generally leads (4) to considerable friendliness and chit chat. The menu of the day in the Grills is different from that in Britannia, and often does not look as exciting, but then there are two alcs, which are more extensive then in PG, and, with sufficient notice, they will make anything else you would like.
2. I’ve never known anyone who had the butler unpack, but they will certainly do it. However, obviously, embarkation day is a very busy day for them, so they might not get round to it immediately.
4. Mostly pretty ordinary people of varying nationalities. Sometimes a lot of US passengers, a lot of German passengers on a crossing starting at Hamburg, and I’ve known a lot of Australians, but also all the other nationalities you can think of, which can make the journey very interesting. I think many passengers are like us, and go on fewer cruises than we might otherwise so we can afford the Grills when we do go.
