I often stay at the Hilton Anaheim on my trips - full disclosure: I work for Hilton, so staying there is a no-brainer. There are no special Disney offerings as the hotel is connected to the convention center and caters to that crowd, though there might be a large Disneyland advertising banner in the lobby sometimes. It may be busy with business people if a convention is going. It is still very convenient for Disneyland and very walkable too - it's further than some, but not bad. I usually walk up the little side street to Katella, but you can also go straight out to Harbor (I like to stop in the CVS for a Coke Zero). Everything else is pretty standard for a Hilton and it's a very safe, if unexciting, choice.
*I already disclosed, but I do have to mention that I am a Hilton employee when discussing our hotels. Thanks!
