The main claim here is that Disney is trying to lower the drinking age to 18 in their parks. This claim was first discovered on a tik tok video posted by "mousetrapnews" which is a news source dedicated to reporting on any and all Disney park related news.
The claim goes into further detail, stating that Disney World was battling Florida government in court in order to potentially receive a resort exemption, allowing them to sell alcohol to those who are at least 18. This story was eventually reported by ABC news, despite the original claim having no factual basis that Disney plans on battling the Florida governent.
This claim can't be found on any other reputable news sites, which makes it very unreliable, as this would be such big news it would certainly gain the attention of other news stations.
Upon doing further research surrounding the original poster, "mousetrapnews", it is clear that they are a fake news site dedicated to posting satirical Disney related articles.
