I'm a frequent traveler and have been ridiculously loyal to Starwood over the past few years and am now closing in at around 300k banked SPG points. I got to the point last week that I drove an extra 30 min in Philly to stay at the Westin downtown rather than a Marriott out by where I was working. It really has been starting to get out of control with the free weekend night promotion even...

Was wondering at what point people have started diversifying. I just used up my last Marriott points today and am realizing that it may be best to build up points in another program for when I need to book non-Starwood hotels for personal stays.

Any suggestions on a good secondary program?
