Here is a first draft of the translation of the text you provided:
The sprawly lake around Disneyland Paris extended in front of her, where she was spending some of her summer days with her sister and her children, with the enamoring verdure around her and the little boats embellished with colors and mingled with shrieks of children and their families, while playing music in a sweet afternoon hour wrapped with clouds and coldish weather that numbs the nerves and fills the imagination with emotions... But she did not see all that, and even the fanciful picture of the ingenuity of the creator did not deliver the fascination of the impressive nature, like it all flew away from the constraints of an immense picture frame to fill the horizon with sound and image..
