Regarding the OP's first question: yes, it is easy to walk from the Sheraton Anaheim (Disneyland Dr. and Ball Rd.) to the parks. The walk takes about 25-ish minutes, depending on your walking speed and the light at the Ball Rd. intersection. Make sure you take the east/left side of Disneyland Dr. at Ball because the sidewalk on the other side ends shortly after Ball. Keep going south on Disneyland Drive. When you get to the crosswalk at Magic Way, you have the choice to cross west toward M&F -- you can take the tram if you want. (Also, if you take the tram back at the end of the day, you'll be able to walk back to your hotel in about 5-10 minutes.) If you want to stay on Disneyland Dr., keep going south until you see the signpost turnoff for DtD. (If you go under the DtD overpass, you've gone too far.) Go left and you'll be walking behind DtD all the way to the tram drop off area (by WOD). You'll see an entrance gate to DtD by Haagen Dazs, if you want to use that. You can also keep going south on Disneyland Dr. until you reach the GCH -- enter there, walk through to DtD or use the entrance to DCA. Hope this helps.
