Agreeing with the other posters...
for people familiar with WDW, the disability system at Disneyland Paris works more like WDW’s previous Guest Assistance Card. DL Paris does require proof of disability, but the system in Europe is much different than in America. In Europe, people with disabilities are ‘certified’ as being disabled and do have cards they can present for special treatment and access. Even accessible bathrooms (other than at DL Paris) might not be accessible without having applied for a disability key to use them.
One of the reasons that disability services at DL Paris works differently is that the DL part of the park was built without Mainstream lines and entrances (Mainstream Lines as accessible thru the regular/main line). The Studio part does have Mainstream lines for most attractions.
For the OP, this link has complete information about how the Disability Access Service ((
DAS)works at WDW:

Only the first few posts are up to date, the rest are from just before and just after DAS began.
If he needs separation from others in line, as others posted, the easiest way to get it is to have him toward the front of your group and have the others in your group behind. That way, he controls how far away guests are in front of him and you prevent getting too close from behind.
Another thing that might be helpful is using a stroller as a wheelchair in line. Almost all attractions are wheelchair accessible in the line to the point of boarding. Using a stroller as wheelchair tag is often helpful for people who need separation from other guests. The stroller becomes a ‘safe haven’ for waiting. The tag is requested at Guest Relations and the link above gives information.
As others mentioned, they will want to prearrange the 3 Fastpasses available to every guest. Once those are all used, you can make another Fastpass, one at a time. DAS works best used with Fastpass.
If they have smartphones or a tablet, I’d suggest downloading the My Disney Experience app. It uses WiFi, which is available in the parks. On that app, you can see all of your Fastpasses, the DAS time that has been scheduled and things like current wait times and attractions that are not running (whether for a renovation or temporary outage).
The app also includes restaurant menus and allows guests to preorder their food at a variety of counter service restaurants.
So, even though it works different at WDW, there are a lot of tools you can use.
