I haven't stayed at the other 2 hotels (and I've heard good things about that Super 8 property), but we stay at the Sheraton Anaheim across from that Super 8 quite often and walk to the parks. For us (no strollers, no mobility issues), it is about a 15-20 minute walk (easy pace, not power walking) from that Sheraton through DtD to bag check. The walk crosses Ball Rd., stays on
Disneyland Dr., gives the option of crossing at Magic Way to get to M&Fs if you want to take the tram, and cuts behind DtD, joining up either by Haagen Dazs or ending by WOD. It's a nice walk and not strenuous. The Anaheim Plaza is probably closer (straight up Harbor, then cross at entry to the tram drop off). The HoJo is in between, but similar to the Anaheim Plaza. If you get a good rate at the Super 8, I wouldn't let the walk deter you. You can always take the tram if you don't want to walk the whole way.
