You've completely missed my point.
Most managers correctly see priceline folk as people with no loyalty whatsoever, who won't spend an extra dime to stay with them in the future, and basically as them doing you a favor with your room being subsidized and made possible by actual rate-paying guests. Frankly, they're often right.
You are also probably going to get put in old/unrenovated room and are lucky to get confirmed into 2 queens or 1 king in advance.
To then ask for a suite, in advance, is a very long shot. It's one thing to ask if they happen to have something when you checkin, but I don't waste my time on long shots nor do I care to be sneered at "oh, I see you're on a priceline rate."
