Assume you mean FF. Since you did not say anything about how long a stay is, what size of bedroom it will be, and when (except you don't need Prime or high).
I used to have 84k. I have used it to stay in 2 BD on east coast for 3 to 5 days use internal exchange.
I now have 231k, if I have to I could be able to use them all for 2 BD for 2 night stay use internal exchange. Never try that, maybe I will do it one day. My recent scheduled trip is 40.1k for 2 BD stay in Williamsburg, Kingsgate Friday to Sunday (2 night 5/11/07 to 5/13/07). Last 2 reservation is Glade stdio 28k for 1 wk at Dec and 84k for Kingsgate July 4th 1 BD for 1 wk
