Are guests isolated in their original cabin or in a different cabin? I've read both that there's an isolation "wing" on the ships but also that some guests have been isolated in their original cabin.
As a follow up to the venue changes: the HAL website description for the Oosterdam now lists neither the Rolling Stone Rock Room nor the B.B. King Blues Club.
Also from the article: "Additionally, on Vista-class ships — Noordam, Westerdam, Oosterdam and Zuiderdam — the line will replace B.B. King's Blues Club with the Rolling Stone Lounge."
