it doesn't look like you are too far from everything.
When we went down, I was nervous also. It was our first "extended" time offsite.
Well, we were at Vistana which is close to DTD. I couldn't believe how relatively close everything was. And I believe we were closer to EPCOT than we were when we were staying at WL. When we went to MK, it took us about 12-14 minutes from our condo to the MK parking lot. It took us longer than that at WL just for a bus to PULL UP somtimes.

I remember one time we waited for 20 minutes for the EPCOT bus. We didn't have many problems with WDW transportation, but we did realize we like taking our van. We must be control freaks or something.
When we would drive around I would be saying, "oh, that's where the Marriott is", or ,"that's where the Hampton is". It all made sense then.
Johnny Old Boy.........where did you get that great map? I wonder if I printed it out if I could read the writing better.
