I'm taking a gamble here with my poor memory but I believe you go straight east. It turns into an expressway/toll road that you pay about .50 to drive on. However, you can exit right down by WalMart (Exit#???anyone) & SteakNShake. Note, the important addition of SteakNShake! It takes about 5 minutes, compared to about 35 driving on 192. We didn't find this out until SEVERAL trips on the stop and go road. AGH! Next time I'm getting my local map from AAA ahead of time so I have time to study it.
PS, they had a ton of Disney clothes, etc. Stop there first and keep the temptation down at the parks in the souv. shops.
