sea world to discovery

[Max Power]

is it possible to walk and how long does it take

Don't understand your question.

The two parks are close together....but you can't 'walk into' Discovery Cove. Reservations required

They have a phone to call if you want a ride from SWF to DC.

It's located at the north end of the parking lot where the busses show up. Exit SWF and walk to the right towards the bus area and you'll see it.

And if you want to visit BGT from SWF, here is the sign for that.

You can walk, but it's kinda far. I'd use the phone and call for a ride.

You could walk, but it means crossing Central Florida Parkway in an area where there is no crosswalk and no light to help you across. Since there's a courtesy phone so they will come get you, it's better to do that than risk getting hurt crossing a major road.
