I am considering a quick trip down to Orlando or Tampa, either April 30 - May 3 or May 7 - 10th. We would be traveling on Fri and Mon., so our park days would be Sat and Sun. This is still way up in the air, in fact I still don't know where we would go, either WDW, Busch Gardens or Universal. How crowded are the weekends at this time of year? TIA
