Ok so just did this again this year, been loads:
Train (Eurostar) goes to Lille and you have to change. The wait time is passed in a small ish station or there's an outlet centre next door.
It's worth, if you are staying in a Disney hotel, going the luggage express - take your luggage up (pre booked) and they send it on to the hotel, you get your entry cards and can go straight to the park.
Marvel Hotel New York is really fresh looking and at the other end of Disney village. Newport hotel is a similar walk. I personally hate Newport Hotel.
Then further away are the others. Some good theming.
Meal plan is good if you eat meals rather than snacks. Vegetarian/vegan is thin on the ground.
There is no supermarket type place in the village or on site so take snacks or buy them .
I would stay on site with anHB meal plan tbh. You get an hour extra before the gen pub get in first thing so an early start but good for some of the queues.
Book through Magic Breaks or Disney holidays
