For a bit more reasonable priced buffet character breakfast check out Cape May at the Beach Club. The food is excellent - they have Minnie, Pluto, Goofy, Chip & Dale as chatracters..it tends to be a little less crazed then othe breakfast character meals and I believe it it one of the lesser priced ones.
If you're not staying at one of the nearby resorts (BW, YC, Swan or Dolphin) an easy way to get there is take bus to DHS then boat from DHS to BC. If you go to EPCOT you will have to walk through all of ECPT to get to international gateway (by France) to then walk or take boat to BC.
There are also cabs.
