Timings are always an emotional topic.
The directions given in earlier posts is the best route if you want to use made up roads. However, there is a route that completely bypasses travelling along the 192, but this involves travelling on a dirt road for about 400m. On turning right out of Formosa Gardens Estates, take the right turn at the 4-way stop onto Funnie Steed Road, then take the 2nd Left onto Entry Point Blvd. At the lights with the 192 go straight on onto Sherberth Road.
Owners will usually make timings to getting to Disneyworld, which in practice is the Disney Arch or the first dsney sign. Using this methodoly Formosa Gardens is about 5 mins away.
However, this isn't a lot of use as this gets you nowhere, the next timing could be the parking lot. From Formosa Gardens this is approx 6 mins, 10-12 mins, 10-12 mins, 15-20 mins to AK, EP, HS, and MK respectively.
The crucial entry into the park timing can vary dependent on the time you arrive. Eg if you arrive early you don't need the tram, as your parked either next to the entrance or the monorail. Arrive early in the morning and the tram is quicker as its not waiting as long at the stop to fill up.
We have been actually in each park from the villa on Formosa Gardens within 10mins, 15 mins, 15 mins, 30 mins to AK, EP, HS, MK.
Hope this helps
