My son is getting married 9/26/15 and I'm doing the wedding cake for 235 ppl.

I don't do cakes anymore but when I did I usually covered the tiers 2 days prior with fondant.  I fridge all my cakes as I use IMBC.  Since the wedding is 2 hrs away and I've been assigned a ton of other things to do for the wedding as well, was wondering if I could cover the tiers 3 days prior and still be ok?  I use Albert Uster's Massa.  Just don't want the fondant to be to tough to cut for my son and DIL.  What do all you experts think?
