Do you have to queue for a shuttle bus at Port?

 From what i'm hearing some cruise lines are charging more and more, with local sevices sometimes offering a free service and just expecting a tip.

Having been told that a 'courtesy bus' was available for a small fee, had me confused! How on earth can anyone know before their cruise what the real costs are going to be? it may or may not be chargeable if for instance you are a Oceans Club member, after talking to a Gold Member who told me that she was greeted with a message on her pillow with the charge of the shuttle bus to port the next day, she queried this and so did'nt pay, had she not then she would have been charged!

Some charge as little as one euro and some at eight, some free some local....
I have spent some time searching on the well know cruise lines sights..and if the information is there, then they are not shouting about it...hmmm.
