We are waiting for ROFR for SSR. We debated BLT versus SSR and to me, the choice was really close. SSR is cheaper (even factoring in the lower MF for BLT). Also, I'm not sure if we would be able to take advantage of the 11 month booking advantage, so buying the cheapest points made sense for us.
We look at it this way. If we stay at SSR, that's fine since that is what we paid for. If we can wiggle into a different resort every now and then (we travel during non-peak seasons), then it is a bonus to us.
On the reverse, if we bought more expensive points, then I would be disappointed if we had to settle for a resort with cheaper points.
Finally, BLT is too urban for us. We live in a city so it's not really much of an escape for us.
