My guess is the safety drill will be at 8.30pm. Glad I'm not a parent of small children
I am sure there will be plenty of opportunities to get the photographers to take a group photo once we are onboard. I have never known a ship's photographer turn down a request to take a photo, especially if they think they might sell 10 or so copies at $20 each (special cardboard Princess presentation folder included)
I can get to the pier whenever really. Princess aka Carnival texted me and sternly told me not to arrive before 4pm but they always do that and I have never been turned away from a pier on turning up early. Usually though it's because I've had to check out of a hotel room, so the luxury of departing from my own city in a cruise ship is new to me
