We are booking a cruise for a family of 4 with 2 teenagers (15 and 13) and are planning on getting 2 separate staterooms with the intent of the teens having their own room (across the hall, not adjoining). I don't believe cruise lines allow us to book this way, so we'd have to have one parent booked in each room. Has anyone done this before? If so, how do you manage the key cards? The key cards will have our beverage packages on it, so we can't swap cards with the kids. just not sure how this will work logistically. Thanks!
