We went to Orlando for 2 weeks in September 2005. We stayed for 1 week in I-Drive before moving here for the 2nd week. Its location for Disney village is fantastic, a 10 minute stroll. Its also near Pebbles restaurant which you must visit if you stay there.
The transportation to the parks was fine, although on some days we did take our own car, mainly because we wanted to move between parks. The breakfast was ok, although we did prefer getting something on the go in the parks.
We got a Disney view room which was well worth the extra $10 a night. To see the Magic Kingdom and Epcot fireworks from our balcony was great.
If you want a hotel in Lake Buana Vista that's not too pricey then I recommend here.
