A regular Epcot ticket is $179, and you get the whole park with every attraction. The party is $110, the restaurants are all closed, all but maybe four or five rides are closed, there are no fast passes, and lines for characters and attractions tend to be very long. In 2019, I think the 3 caballeros character line was 4 hours at one point. It makes much more financial sense to buy three park tickets instead of three party tickets.
