its actually cheaper than a one-day ticket, if you want to go to DCA that is, its not like they close everything
like the $134 is the cheapest, party is 6-11 but get to go in at 3pm so you get 8 hours, a lot less crowd so you get to do anything and everything since dca is already small enough as it is but if you want you want to go on rides, most are walk through + a bunch of halloween activities, etc…
in comparison - weekdays in june and july are $169 and $184-$194 on weekends
if your going to disneyland then thats a whole different story because you can stay from open at 8am til midnight there and still not do everything
price does go up the closer you get to halloween but just got to be smart about it
