To stay clear(ish) of Hurricane Sandy Carnival rescheduled us to leave New York a day early and swap out San Juan and St Thomas for Port Canaveral and nassau. This extra day would be free of charge but came at the expense of the previous itinerary who lost 2 of 3 ports and a day of cruising.
Departed NYC at 5pm (an hour earlier than scheduled), the last minute schedule changes had us a bit concerned but we were confident Carnival would keep our safety their priority.
The seas started getting bumpy a couple of hours into the trip. By 8pm our closet doors were opening and slamming shut on their own. We stayed in our cabin for the rest of the night and by 2-3am our drawers had all slid open, all our clothes had slid out of the closets and we were forced to relocate all breakables from anywhere they could fall and break. Walking to the bathroom took a bit of time/skill.
The balcony of the cabin above is directly over your bed so chairs can be heard similar to being below Lido deck.
