I'm coming to this party late, and I don't wish to judge what anyone has posted, but I will say this: when you make your choices and pay for what you can afford, you shouldn't expect anything more. If pixie dust lands on you, there is nothing wrong with taking the free upgrade

. If you are brave enough to ask for a free room upgrade (I wouldn't), I don't think it's appropriate to complain about receiving no for an answer.
I once got bumped to first class on a flight. I didn't ask to sit there, but the agent GAVE those tickets to us to fill the flight, so we took them. I know it made other people angry that we sat in first class for coach price, but that wasn't our fault; we even offered to sit in coach so two other passengers could have the better seats, but the agent at the gate said we should keep them and not feel guilty. I've never heard of anyone
asking to sit in first class for coach price, but if they did, I'm fairly certain the answer would be "no." How is that any different than booking standard room and then asking for preferred?
Disney, like all other companies in the travel and entertainment business, has rules. Those rules are in their own best interest, as they should be. They are also in the best interest of ALL of their guests, because if I don't pay for something and just decide to take it anyway, I am taking it FROM Disney or one of the other guests. I don't want to be on the wrong end of that situation, so I won't put another guest on the wrong end, either. In that sense, this IS a situation where wrong and right are clearly delineated. Breaking those "rules" eventually drives costs up for everyone.
I don't make a lot of money, and it would have been nice to come to WDW twenty years ago, but I couldn't. I am fortunate enough to be able to take my family to Disney now, but breaking rules that cost other people money or inconvenience, even, is not something I would do. If I couldn't (or didn't want) to pay Disney's prices, I wouldn't blame Disney or their paying guests. I would just have to work harder or save longer or not go. I really don't see any justification for skirting the rules that are established to guarantee that a company survives and that their customers are treated fairly.
