You have to give Carnival credit. they have really made the Hub app an indispensable and great tool for cruising. For someone like me, who has to stay connected anyways; it's great to have my Fun Times, instant dining reservations, menus, account summary, phone, e-mail, and camera all right there in one spot. Much easier than carrying around different rolled up papers, going to check various menu boards, going to guest services for my account balance, having to call for room service from my actual room where I'm told it will be ready in another hour, etc.
I know some folks just want to or need to die on the hill of keeping their phones locked away. That's perfectly fine. But I definitely forsee the days really soon when they will not have any printed menus, fun times, or guides.
I bet you they'll still hand you a printed out port shopping guide without fail though.... ðĪŠ
