That’s exactly what I did. Signed my deal back in July on 300 RIV points. At that time, the incentives that expired mid-July were better than the pre-Welcome Home weeks incentives on 300 points. My final payment was not scheduled until late September. The Welcome Home weeks incentives came out and my deal was re-written with the new incentives. I went ahead and paid my balance and have already closed - figured nothing better was coming and just wanted to get on with it. But, could have held out a little longer if I had wanted to.
I was initially concerned that once you past your 10 day rescission period, Disney could just say, well tough. You’re locked in and we aren’t giving you better incentives. But that was absolutely not the case. My guide was basically like, sure, we can absolutely re-price it.
