Perhaps the middle of the night coffee is contributing to your inability to sleep?
Not sure if you've cruised before so forgive me if I'm telling you something you already know. There are plenty of places to sit and relax, inside and out, even if there aren't lounges or restaurants technically open.
So what are the latest/earliest places to open, and around what time? My 70yo dad might wake up early... What would be the most pleasant route to walk, say around sunrise time? Can it get "cold" in the Caribbean in the early morning (we're going in September)?
Hey does anyone know if CMs do "night patrol" in the public areas during off hours? Just asking because my elderly parents (who will be first-time cruisers) would be concerned about safety. I may be concerned too if one of them happened to need help and can't get the wave phone to work.
