Lynx blows. I tried to use the Lynx bus stop at Downtown Disney and gave up. The bus only comes every 30 minutes (!!) and the bus stop is just out in the open. You'll cook to death long before the bus comes.
We missed the bus the first time because it came far too early (we were on the other side of the street, and it came and left) and then the second time, we waited and it just never came. Waited 5-10 minutes past the scheduled time and gave up because it was just too miserable and hot.
