I've been Plat for 10 years and will make it for 2015 next week. I have a fantastic upgrade record, and the last few hotels I've been to have treated me quite special. I guess maybe it depends where you stay? Be sure to ask at check-in if no UG has been assigned, but I've rarely NOT been upgraded. I've stayed in suites all year, getting upgraded in NYC, Cancun, Detroit, Chicago, Hawaii, etc. In fact I've been upgraded in ADVANCE for my stay next week in Orlando.
Sometimes it happens, sometimes not. Luckily for me, it's more often than not. I'm getting close to my Lifetime Plat status (already made Gold) and I guess I'd say that's next for you.
