I'm not a lawyer. I'm not sure that having a sister in law who is a partner in a top 10 law firm working in Trademark law helps me have any extra info (except that I now know why George Lucas went after anyone who made anything remotely Star Wars'ish...becuase you must defend your trademarks vigorously or you could lose them). But a quick read through the
Terms and conditions of the Disney site showed me some things that Disney might use against these sites.

https://disneyworld.disney.go.com/park-experience-terms-conditions/ (which despite its URL name is actually listed under MyMagic+ T&C) doesn't seem to have anything governing use by a dining site. But I found this interesting tidbit. If we use the site to change FP+s etc while walking through a park, we're going against what we agreed to by using the site. "We advise you to not use this Site/App (including the camera) while driving, walking, or when being distracted or disoriented from your surroundings as it could be hazardous."
