Oops, I misread your original pot, my bad, didn't think you had read that yet.
Disneyland is so much less about staying on property than it is about the parks. There are pictures of each hotel on the website and descriptions of the amenities, there are also posts here that describe each hotel and the amenities. I really enjoyed 5 days at Disneyland in the Embassy Suites just as much as I enjoyed WDW in the CBR Pirate themed room. We actually spent some time in our room at WDW, so it mattered, but we barely spent any waking time at all in the room here at Disneyland, so it didn't.
You have to decide what's important to you. Personally I'd stay at a far less expensive hotel and add 2 more days to the trip.
