Being a novice in SPG, I did not know that about reward night bookings!
IS that for any member Vulcan? If one books weekend nights at a hotel, usually they cost a lower point value at lesser properties, say for 4 consecutive nights including a Thursday night, is the follwoing Monday free?
If so, that sounds really great!
By the way, sorry for mistakenly thinking that you were not top tier in SPG. However, my comments are all the more accurate if one is heavy on credit card point earning and relatively light on stay/travel night accumulation, for SPG's no blackout rule will work quite nicely for those individuals, although the relative class of the room will of course be better to those who hold elite status in SPG.
