I've had several calls over the past couple of years. As with AF1, after I had researched some cruises on the Royal Caribbean website I received numerous calls which went unanswered by me. I finally picked up the phone on one of their calls and told them I had a cruise already booked through my agent. RCI was persistent. So am I in screening calls but I finally got sick of it and now I know to nip it in the bud early or else they won't stop calling.
Carnival did the same thing after I did nothing more than go to their website and order a hardcopy brochure. A PVP called several times before they gave up. In that case I never talked to them.
