A little preface. I was a platinum member last year and got 5 nights free at all CET properties. Since my first time in Vegas I won 6000 playing blackjack I suppose. With my offers for my second trip, I ended up staying at Augustus Tower with fountain view which was great. I didn't have the same luck this time. I lost 3000. Consequently, my offers decreased big time. I am planning on another trip this May. I checked yesterday and I could get free rooms at Harrahs. 20 dollars for 4 nights at Flamingo and about the same for Ballys. So I am probably going to stay at one of these three places. Then I looked today and it is about 70 for 4 nights at Harrahs. about 120 for both Ballys and Flamingo. Does it fluctuate this much?
