The longer your wait for assignments the better the odds of being upgraded. The only reason not to close the catagories that close to a sailing and assign them is that they still have higher ocst Cats available they want to try and sell for more $$$ if possible before giving them to the Guar bookings. If the catagories above your sell out or all cabins sell out, they'll make the assignments. You may not be the one fortunate enough to get one of the hold out cabins but your odds improve when you're among the last assigned. Cross your fingers and as Larry said, let us know what you got when you get back.
