We are doing WDW from May 16-22 and I would LOVE to take my 4 y/o to Sea World one day. Would I be absolutely insane to do it on a Saturday or Sunday during that time? Do the crowds increase greatly on the weekends?
Crowds are larger on weekends but it isn't the line after line like at Disney. Shows are in stadiums so you just have to find a seat. You should still be able to do everything and have fun no matter how many people are there.
