I have not posted up on this forum in years, but I was looking for a piece of information and came across your message.
ECV's are not a common sight in France and the only times I remember seeing them were when guests from the UK visited the park. I would second Karin1984 suggestion and strongly advise you to stay on site.
I would like to point you toward this link:
https://brochure.disneylandparis.com/HCP/UK/catalogue/index.html They are the guides for guests with disabilities and there are few different from WDW and DL things I would like to point out:
1- Peter Pan's Flight require guests to be capable to walk and go down ladders on their own. Space Mountain, the Indiana Jones coaster and Crush Coaster used to have the same requirement, but it was relaxed a few years ago and only Peter Pan still has it.
2- This is directly from their website:
Documents required to apply for an Access Card
Priority Card: for disabled guests (anyone who is officially registered as disabled).
- French residents: disability card, disabled person’s priority card, difficulty standing card, war disability card, European disabled parking badge.
- Residents of other countries: disability card, European disabled parking badge, other official documents issued in your country of residence, war disability card, a medical certificate (original copy) in either French or English, issued less than three months previously and signed and stamped by the doctor, certifying that the person has a permanent disability.
Easy Access Card: for guests with a temporary illness and for expectant mothers.
- Medical certificate (original copy): in either French or English, issued less than three months previously and signed and stamped by the doctor, certifying that the person has a temporary illness (e.g. is wearing a cast, has recently undergone an operation) or is pregnant.
Basically, in order to get a card to use the exits and other special lines,
Disneyland Paris has those requirements.
3- Ratatouille, Buzz Lightyear and Its a Small World have wheelchair accessible vehicles, but you will need to transfer to a wheelchair from your ECV.
4- Space Mountain and Big Thunder Mountain have a narrow 45 seconds window to board and get your restraint verified when running at maximum capacity.
