Thanks. I saw those. Being a points novice, I just assumed there would be a bunch more. Thus, the naïve "not seeing a whole lot of options" comment.
Also, I was taking the Marriott fees into consideration when I came up with the $6.90 pp estimate (which was calculated from averaging 3 of those 4 ads).
I will check eBay completed sales to get a perspective. Do you have a feel for the various increments sold? I would need 3,750 (15 shares) to achieve the Executive ownership level. I see sales down to 1,000. Not that it's a lot of money for back of the envelope calculations, but if I'm doing "what if" comparisons to what I purchased from Marriott Sunday, should I assume I'll only be able to get my required shares by purchasing 4,000?
Thanks, again.
