As Ali said, your English is excellent. I don't think you'll have much of a problem understanding others there. I've been to the Disney resort, and in my opinion, I think EPCOT is the second best park you can visit. It's a lot of fun, and it's main focus is educating people in a fun way. The Magic Kingdom, the main park, is my favorite. I only recommend visiting it at night though, that way the lines will not be as long. I hope you have a great trip.

Don't worry, your writing is pretty good. I do believe you won;t have any trouble with your vacation in Florida. I just had been to two Disney park in LA. I heard that there are four theme parks in Florida. If you had enough time you can explore all of them but suggest you keep one day off between two parks. cus it is really a lot of standing and waiting. And you can download the Disneyland APP, which has provided the detailed info about the directions, the waiting time and show-time for every roller. And Have a nice trip
