When we got cancelled off last thanksgiving from the Panorama I got on the waitlist for 3 rooms on the Mari Gras Paid the deposit and never heard back from them, but I called the 800 number and spoke to random people over the next few days and was able to book all 3 rooms at different times I called (one at a time). Don't wait on them or your PVP, call Carnival directly, the rooms pop up randomly and go quickly and no one but you will watch it in time. Check the website, you probably won't be able to actually book it it will say you have to call when it shows up, so call them right away. I did get my deposits back from the waitlist after a few weeks of sailing as they won't use that for your bookings, so for a few week we had money out to them, but it all worked out and it was a holiday sailing. It just takes persistence on your end and good luck
