Sale Dilemma?

Hello All,
I am in need of a little advice if possible please
Myself, the significant other half and my in laws are off to sunny Florida in November for a few weeks. We caught a real bargain in the last sale, bagging Y seats for £389 pp (M+M)which is pobably the cheapest I have ever seen so was well chuffed with my little self.
My niece has now decided that she wants in on the action and so imagine my surprise when I learned there are now no M+M fares available on the dates that we are travelling, despite there being stacks of seats available both out and return. A normal ticket is coming in at £552 which, reluctantly I am prepared to pay however, and here's my dilemma, Do I go ahead and book it now at the inflated price or do I hold off in the hope that there may be another sale?????? or that the MPM fare reduces somehow.
Any thoughts or advice is greatly appreciated as always oo)
Regards,
NOC
