The description of a politics card B is
" All rooms in at least 2 columns of your Hotel board are occupied "
Does it means that columns need to be adjacent?
I don't think they need, but the card icon shows they are adjacent.
Am I right?
I don't see why you'd think they must be adjacent if there's nothing about adjacency in the rules.
Basically I'd guess you're over-thinking it. An illustration would have to show either adjacent or non-adjacent columns, and shouldn't imply anything in that regard. If it showed non-adjacent columns in the illustration, would you ask whether adjacent ones were permitted?
