Hi, I'm thinking of booking a cruise to Alaska from Vancouver (return) with my family. I have two teenagers. Is it worth the extra to get a suite? Is there anything additional included with a suite? And is it worth getting a drinks package? I understand internet access and gratuities are extra. Apart from specialty dining, what else are extra costs? If one of my kids is over 18, is it possible to get put them in a separate connecting room or are they considered too young to stay on their own? I'm just trying to explore different options for the four of us. I've been looking on Royal Caribbean's website and doing Google searches, but it's difficult to find all the answers. I know it's a lot of questions, so I appreciate all answers. Thank you so much!
