How can we fit these 5 parks into 4 days? (orlando)?

How can we fit kennedy, typhoon lagoon, epcot, universal studios (not IOA) and magic kingdom into 4 days? We only have 4 days to do it so should we drop one or would it be possible to do two of these in a day and which order would you do them in? (i.e MK morning TL afternoon?) Any information would help really :) Thanks in advance :)
