IMO, we are in a strange time of service back-lash. For awhile, the customer was always right and compensated as such. Then, a rash of an attitude occured where customers expected compensation from any complaint. Now, a lot of people (service industry or not) think that if you have a complaint, you are aiming for compensation of some type and are far less sensitive...assuming that this is just another customer wanting something for nothing. These complaints of the OP are valid, but even the DIS posters are less sensitive.
WDW will have to improve to survive in the long run. With the cost of gas rising, less people will be able to afford the rising air fare prices or the cost of driving to WDW from long distances. They will lose business in the upcoming economy. In order to keep business, they will need to provide the top notch product we love. Excuses such as language barriers with housekeeping, or tired CM's, or lack of bellhops won't bring the customer back. They'll spend their hard working earned vacations elsewhere.
