JC, I think you should be able to call Member Services and bank them now, even before you sign the contract.
It looks like LoveMugsNPins was able to bank them even with the contract snafus. Hopefully they'll stay banked!
I know every experience isn't the same, but I bought RIV a week or so ago (signed 09/14). I was so intent on asking questions about Fixed Weeks, I forgot to tell my guide I wanted Oct UY. He automatically assigned April, which isn't great for my Fixed Week 44 - first week in Nov. He had to get approval to change to Oct, but they agreed. I received the revised contract the next day.
I banked my 2019 points after signing the contract but I've seen other reports also that you can bank immediately.
