Are there any?
I would say:
- Not being able to stay in ports as much as you like/at night
- Gaining a few kilos extra as food as available 24/7
- Not being able to find a truly quiet spot (except for your cabin)
- Waiting in long lines to get off the ship/back on if it's a tender port
But still, that would never deter me from cruising
