Best place to look is online.
It's going to be around $500 plus $25 for parking.
Book in advance, it's cheaper and you can get some fast passes.
Depends on how old the children are and how long you are there. But over 10 are 110 a day or 85 a day if you get a 4 day pass with one ticket to each park.
Probably atleast $500 but I can't be sure. Just a guess
