We will stay in SSR and would like to spend a day in either SeaWorld or Universal Studio - due to seniors (grandparents) and little ones (DD4 and infant) in our party, we can't spend much time - maybe 10:30 - 20:00 (including travel time). Which one shall we go for goodness of our DD4? P.S. Shall we drive there or take a town car? Which one is closer to WDW?
