I think a LOT of people who stay outside of WDW, particularly in parts of Kissimmee and on I-Drive might argue that statement. In fact is seems that there is an overabundance of Days Inns in the greater Orlando area.
I didn't say that no one STAYS at those motels, I said they don't GO there for their vacations. Of course people stay offsite at all types of places, but I doubt they consider a standard motel their vacation destination. One could easily go to any WDW resort, never leave that resort, and yet still have a perfectly wonderful vacation. I don't think that can be said of the local Motel 6.
To describe any WDW resort as being even close to a regular motel just isn't accurate. That's like saying non-fat milk is just cream without the fat. The only thing the All Stars have in common with a standard motel is that neither have interior corridors. That can be said of many of the WDW resorts.
Personally, I don't see anything wrong with any of the hotels, motels or resorts that have been mentioned. To each their own and what their own personal preferences are. We've stayed at some of the most expensive WDW resorts and we've stayed at Days Inn type motels. It all depends on what you want and what you can and are willing to pay.
