Let me tell you, you are going to have a great time at Vero Beach! It's really easy to get there... It's about an hour and 45 minutes if you don't stop.
Fly into Orlando and then take the Beachline (SR 528) East toward Cape Canaveral/Beaches. From there you just hop onto I-95 South and take exit 156 toward Sebastian.
The resort is about 14 miles from the highway, over a big long bridge, and onto the "island" side. Once your over the bridge you see the Mickey head topiary in the grass, turn right... then the entrance is about 100ft. on your left. It's so secluded and private. Have a great vacation!
