I just read an interesting question on Facebook about "Chair Hogs". Carnival has a chair hog policy but I don't know about other cruise lines.
What would you do?
Someone put theirs stuff down on the deck chairs and leave for hours.
1. Walk on by and say nothing.
2. Bring it to the chair hog's attention.
3. Let the ship staff know about it.
4. Move the stuff and sit down.
