We have the best Big Thunder Mountain and the prettiest castle, also the prettiest park. Disneyland Park is also designed to stroll through. And I also think our Pirates is better than the US versions ;-)
If you are into shows, I would definitely go by Mickey and the Magician in the Studios (I hope it's back by then). Also the Disney Jr. Show, Lion King Rhythm of the Pridelands are really good.
Paris has some distractions, like the Aladdin walkthrough, Alice' Labyrinth, the gallery in the castle, the dragon under the castle. Take time to stroll if you are into the small details.
Food, to me, table service in the park is overpriced, also quality is better in the US parks. It's not bad, but I prefer eating in Disney village.
And for culture, yes, knowing the difference between Anaheim and Orlando is a start, but this is France/Europe, not the US. It cannot be emphasized enough, as it's the one thing Americans overlook and sometimes come back disappointed. For hotels, in case you are not familiar with European hotels: Hotel rooms are smaller, beds are harder, and no/hardly AC.
Overall, Disneyland Paris has some good things, some less good things. There is magic, you do have to be willing to see it
When in May will you travel? The first week of May is a holiday week for most of Europe and can cause crowds.
oh no! I’ll be there the first week of May. There goes Disney
