as outjers have stated 14 days is a long time in cali.we did a drive up to vegas for a 5 nights.Found that universal orlando is beter than florida one.Disney at first wa a disapointment (think seeing the smal castle did it)found Knots berry a good park,and san deago zoo well worth a trip.
You could do disney easy in 3 days,1 day for universal,1 day for san deago zoo, 1 day knotts berry farm and a week in vegas
dont go in may as its a bit chilly in the water aug is hot and dry,vegas hot all year round
