We are going to Sebastian Fl the first week of April. I thought it would be fun to take my girls to sea world and Aquatica. Do you think we need to do 1 park each day or half a day at each? They are 5 years old and 8 years old. Also, if we do both, is the best deal the multi park tickets on sea worlds web site for ADULT $114.99 CHILD $106.99 the best price? Would it be cheaper to spend a night in Orlando instead of driving the hour and half back and forth for two days?
