Harrah's Rincon Casino in November will offer the same GGWU bonus it had in October: if you swipe your card on certain days you get bonus points.

The dates are Nov 8, 9, 10, 17, 23 and 24 which are too late for the Nov 7-11 GGWU at the Flamingo but okay for the December GGWU at Caesars Palace:

December 4 - 8, 2013
Caesars Palace
10:00 a.m. to 6:00 p.m. PST

In November, each "date" was worth 31,250 points for a swipe for me-- plus extra points if I played. How many points you get varies with your play history.

This gives me a reason to not go to the Flamingo event and to add more points for the December event.
