I want to take my girlfriend on a cruise next year and I want our own balcony and hot tub out on it. I seen a video of a hot tube in a royal suite on the royal Caribbean cruise and my girlfriend REALLY likes those so I HAVE to get one...I looked on their website and it says I would have to all first but I would rather not. I was just wondering if someone could tell me roughly how much it would be for a 7 or 8 day trip in a royal suite...any estimate would be helpful because I just need to know how much I'll need to put back
