Irish Cruiser

Hi I seen on a forum that if you test positive for covid while on a cruise you are quarantined on the “red zone” deck which tends to be decks 2, 3 or 4 depending on the ship. Is this true and if so does anyone know the deck on independence? Meant to be on deck 2 with my family for an upcoming cruise in April and a bit worried that we may be in a dodgy part of the ship in the current environment.
