Not sure on Silver Lake.. from Windsor Hills I would say AK is less than 5 minutes, Epcot I've done it door-door in 7 minutes (did catch both traffic lights green though and I already had a parking pass).... MGM is 5-10 mins... MK is probably 15... to the parking lot, not counting tram time and boat time to get to the gates of course, for that I would allow an additional 30 mins.
I just did a google map that shows the distances and parks but my postcount is too low to post it still!
