For me I still do stays: The bonus airmiles and 1000 welcome myway welcome points are worth more than my actual earned points for the stays at Hilton (i.e. my rooms are typically only ~$150 so that means I get approx 1500 points + 50% bonus... perhaps 2300 points). Adding onto that 1000 more points and 1000 bmi airmiles per checkin (though the airmiles for BD rack up for up to 3 days) means its still worth doing hotel hopping (especially since most airlines only give 1 lot on fixed miles).

But, I'm more commited than most, are a lost 3000 hilton points worth the inconvenience of hotel hopping 4 nights a week? Only an individual can decide...

(And FYI, I've actually gone back to Marriott for stays now for their promo as Hilton's latest promo isn't particularly good since I have plenty of airmiles already)
