Disneyland Paris is a magical place. But if you are used to the US parks, you may get an unpleasant surprise or two.
Firstly, the weather. You are in Northern Europe. Most of the year, the weather is not great. In fact it often rains. It gets cold. Take suitable clothing for the two hour queues.
Secondly, it is cramped. All the rides are much closer together. That means that it is hard to get away from crowds of people. If you like lots of space, this may not be for you.
But apart from that you will have a great time. Enjoy it.
