Move-up shuts down 72 hours before the sail?

[LB_NJ]

I am wondering if anybody knows why MoveUp shuts down 72 hours before the cruise however they continue to sell cabins with less then 48 hours to go?

Move-Up is run by a third party company and needs to be closed out so Celebrity knows the final room count available?

My experience is that sometimes at  72 hours they lock the bids to any further changes but don't actually send out rejections until 48 prior to cruise dates.     On recent cruise I was still able to modify my bet up until the 48 hours.

 

Often  if they lock you out at 72 hours it is a good indication you may have won an upgrade and they are processing it.
