Okay... let's put on the parking brake first.
Are you going to Crossroads to do Grocery shopping? If so, $$BIG$$ MI$TAKE... lol...
This is what you need to do.
When exiting Fort Wilderness, take a LEFT. You are now on Vista Blvd. (Not to be confused with Buena Vista Drive) Continue down that road until it dead ends. You'll pass through the Distribution Center area, as well as Buena Vista Construction Company. At the end of the road, you will want to take a RIGHT. You are now on 535. But not the 535 you are thinking of.
Drive carefully on this road... there is a VERY sharp corner, and they are doing some major construction. Obey all posted speed limits, and drive with caution. You'll feel like you're in the middle of nowhere, and then all of a sudden you'll reach Tourist Trap Central. There will be the Ale House (great restaurant & sports bar) and a 7-11 on your left, and a Texaco, Subway, and Sports Shoe place on your right.
If you go straight, you will go onto the Palm Parkway... there's a Pizza Hut, Olive Garden, and a bunch of other things on this road.
If you take a RIGHT... it will continue as the 535 that everyone knows. Crossroads will be on the LEFT. There's a bunch of restaurants in there. If you continue on, you'll run into I4, as well as some outlets, and a Walgreens Pharmacy.
If you take a LEFT... you will run into two shopping plazas on the right. The first has a few restaurants. The second has a brand new Winn Dixie. This is where I do my grocery shopping. Good prices, and never any lines. There's also an ABC alcohol store there, and a Walgreens Pharmacy.
To get back to Fort Wilderness... go back to that road that the Ale House is on... that is 535 still. Follow the road... once again, be careful about the construction. Take a LEFT onto Vista Blvd... it'll be marked at a stoplight intersection.
