What can I do in Orlando in 6 hours?

A 6-hour half-day at the parks, done right

A pre-dawn pickup for rope-drop at Magic Kingdom or Universal Studios

A hard stop after the morning crowds build, back to the resort to rest

A late-afternoon return if the day calls for a second run, or dinner in the resort corridor instead

A half-day at the parks beats a full one that ends in a parking-structure rideshare surge, the arrival and the exit are the exhausting part, and a chauffeur who knows which gate handles both.
