Don't agree at all. I get upgraded all the time without ever asking - paid rates and reward nights. Rarely, do I not get upgraded. Does not make a difference if it is a one night stay or a week long stay (or longer). Just depends on their occupancy projections and the way the hotel treats elites.

I'm already pre-upgraded at a Staybridge Suites I'm staying at in three weeks for over a week. One that I stay at often. At a Crowne Plaza I stay at once in a while, they've already looked at my reservations (modified) and upgraded me for one stay but not another during a busy set of dates. I can count on the Holiday Inn in Torrance to pre-upgrade me to the club floor the day of or the day before my stay everytime. Staybridge Suites in Miami upgraded three rooms I had for myself and friends/family during the same busy dates in March (I was there for a week).
