THIS. YES.
I much prefer DL to WDW, and this is a big reason. I love being able to walk to the park at my own pace in the morning and to hop back and forth to my hotel room without any fuss, and NOT having to wait for a shuttle when I'm tired at the end of a long day. It's worth more to me.
Now, if those things don't matter to you, then there are LOTS of off-site hotels near DL that are much cheaper. Some of them are quite nice, but all are futher away.
