So what's the "house package" and how many people comprise a 'group' in order to purchase this? What ships is this available on?
The house brands are the cheaper brands of liquor. According to my TA, in order to get the drink package you need a minimum of 50 adults in your group. The alcohol drink package is available on all ships.
FYI....on Norwegian Cruise Lines you only need 20 adults in your group to get their alcohol package.
