Do u have to pay to get into each park?

Yes, unless you get a "hopper" ticket, of course that costs extra.

If you purchase the Park Hopper ticket you can do both parks. Otherwise it's one or the other.

Yes

Yes unless you got a hopper at a hotel then it comes on the card but of course got to book something and I can come with the Box but if you don't want to yes you can it's okay and I'll probably be a lot but we did is we books and we got a box of the hopper and that's why we don't have to pay

You can purchase a one day pass for one park, or for both. Of course the park-hopper pass will be more costly.

Yes, you need to. There are 'Hopper' passes that allow entry to both, which would cost lesser than, it would if you buy them individually to each park.

Yes, however the hopper option isnt probably a good option unless you would like to do just a few rides or you have been there before.

You could buy a park hopper ticket which allows you to enter into both parks or you could buy a regular ticket which allows you to enter into only one park you also have to pay $20 for parking
