I am currently on Quest, think we have around 580 passengers and had previously been on Journey with 250ish
re Windows, there is an outside seating area called the Sunset Veranda, tables are set up with glasses, cutlery etc and you can order and be served there. Menus have been on a theme each night, last night was Thai night, there has been Chinese, Italian, German etc and will be expecting British and Indian nights. smallish menu, usually 3 x starters, a soup, 3 or 4 mains and 2 deserts.
Difference with passenger numbers and entertainment. With the smaller numbers there was one showtime each night, with the bigger numbers there are two.
