You can use a taxi to the nearest Lynx Bus Stop which is about 2½ miles. Then take a bus to the Lynx Central Station, transferring once in Altamonte Springs. Then get a bus from the Central Station which is express to WDW, with one stop at Sea World en-route. Total fare would be $4.00 per person plus the taxicab. Elapsed time, per the Lynx ride computer, would be four hours and 28 minutes. You could get off at DTD and then get a Disney bus to Pop.
Taxi from SFD to WDW would be about $100 one way.
