Our first RCI cruise is this September, we booked early at a good price but without a drinks package, we don't drink a great deal so I doubt a drinks package would be worthwhile, especially as we will be Diamond from our Celebrity cruising and hope to take advantage of the free pre dinner drinks offers.. However from our experience over the last few years on Celebrity, as drinks packages have become more common the price of drinks has increased massively, great for the cruise line but not so good for the passengers.
