I am a DLR vet who just got back from my first trip to WDW. IMO, staying onsite at one of the three DLR hotels does
not carry the same advantage as it does in WDW. In fact, you make life harder on yourself if you stay at DLH or DLPP because the walk to DL is more substantial. The GCH is of course right there.
Staying off-site at DLR does not carry the same minor stigma as it does at WDW. WDW vets like to talk about Disney "immersion", but it is just not the same at DLR. We stayed at the DLH once in 2000 and have stayed at some of the good neighbor hotels since then. Heck, we stay right across the street so once we cross a cross-walk on Harbor we are on Disney property - about a 30 second walk.
Most of the good neighbors have some minor DL theming so it is not like you are far away. One of the hugest advantages of staying at DL's GCH or one of the close by good neighbors is the ability to walk everywhere and do it quickly. Check out this map of local hotels around DLR:

We stayed twice, for example, at the (Best Western) Park Place Inn on Harbor. From our room to the DL and DCA gate was a 10 minute walk maximum. No waiting for buses or boats or monorails.
And the distance from the DL gate to the DCA gate is about a one minute walk. And from these gates the distance to DownTown Disney is about one minute.
If you choose the right hotel, moving around DLR and DTD is extremely fast and efficient, and park hopping is extremely fast and efficient.
Some people do not realize this and choose a hotel that is a little further away. We did this in 2003 when we stayed at the nice Howard Johnsons. It added 5-7 minutes to the walk each way, and when you add that we take afternoon breaks every day it took its toll. Never again for us. We will always stay right there on Harbor or - some day - at GCH. As a side note I would like to try GCH but we have four kids and the DLR hotels are set up for families of 5 or less. So we would get stuck having to get two rooms or some super expensive suite. So no GCH until we have money to burn or a smaller group.
