We will be on the Oasis of the Seas this June for 7 days and have opted for the DBP. I am aware that you receive the souvenir cups but doubt we will want to haul them around or even use them. My question is, are we able to give these to someone else on the cruise or is this an issue due to their RFID code allowing people to gain access to free drinks at free style machines? Not trying to break any rules, just trying to figure out a use for these cups without having to use them ourselves.
