For us, definitely a room with a BIG window! Great view from it, and both the ship and room were beautiful, but still prefer a traditional balcony. Not that we wouldn't book an IV again, but not our first choice.
Not sure why you have such an issue with sharing a link to help someone out. Most experienced cruisers understand nothing is guaranteed to be as posted, especially nowadays, regardless of the source of the info. Seemed like a helpful list to give them an idea of what there is.
Celebrity has excellent singers and musicians, but Royal can really shine with their production shows, especially the Broadway shows. We really like "In the Air" on Liberty and Saturday Night Fever is OK. Wife likes it more than I do. Many of Royals guest performers as the same that we have all seen on almost every ship/line. And some are people we don't ever care to see again!! (Frankie and the Dreamers)
