Yeah--the guy just asked us to keep it under wraps and not make a big deal of it. However, we noticed he did the same for others who saw what we did. Actually, it made sense to us--why would they dedicate the retail space and then tell people they would have to save it until the end of the cruise and haul it home with them. We will try for the same deal on RCCL and see what they say.
I'm not sure about the total limit is, but the deals are never good enough to warrent packing and hauling it with us home.
