I just reserved a pass for $149 for a 7 day cruise. I tried confirming with Princess that it was unlimited use for the duration of the cruise, but I couldn’t get a straight answer. Does anyone know based on past experience? Do we need to reserve a specific time or can we drop in? And do we have to pay an 18% gratuity each time we use the pass? I’ve wasted so much time on the phone and live chatting with Princess, but no one seems to know for sure. Thanks,
