What's a good Android app for keeping track of my Norwegian cruise booking and all those little details you get bombarded with?

Okay, so I've been using the Norwegian Cruise Line app for our upcoming trip, and it's actually pretty handy. It took me a few days to figure out all the features – why do they hide the settings button there? – but once you get the hang of it, it's like having a teaching assistant in your pocket. You can see your booking details, shore excursions, dining reservations... all that jazz. My students showed me this trick where you can set up notifications, so you don't miss anything important. I'm still old-school, but even I can appreciate that! Plus, it's got maps of the ship, which is going to be a lifesaver. Last cruise, I swear I spent half the time wandering around like a lost freshman. I'm hoping this will make things a bit smoother. Makes planning the trip less stressful, which is always a good thing, especially after a long school year.
