This is just my opinion, but points is points. Yes we all want to win more & win often, but it's an instant win of points ranging from 50-20,000, along w/ 4-night stays at individual brands & the GP prize of stays at all 29 brands. I don't regard that as a shoddy sweeps, but that's just me. I know a # of people who have entered & aren't pissed off at Marriott. Perhaps that's something unique to FTers?
It's worth entering at least once, as it only takes 1-2 minutes, & odds are you'll win something. If you (generic you) win, great re: whatever it is you won. Move on & don't waste the energy of getting irritated/pissed off. Save that for the true issues, like the lousy IT integration! If you're interested in the GP, then keep entering knowing that's all you're in the running for after the first instant win.
Cheers.
