Disneyland Paris doesn’t have the attention to detail with customer service that you get in USA, which is to be expected, but the main park areas are beautiful - it’s much bettered planned than Magic Kingdom with sight lines etc.
The adjacent studios park however is really dire
Another difference is the clientele - going to a US Disney park is generally a mega event, a long vacation with matching t-shirts for families etc. In Paris it’s school trips and tracksuit bottoms, so you do lose a bit of that ‘OMG we’re here!’ vibe… still, it’s nice.
Oh and the food isn’t so good…
Alright it’s not as good, ok?
