There have been several threads about which day of the week to visit each park, but the title of this thread is the easiest to find so I’m putting this here.
TP Blog had an article about crowd updates which included this handy chart:
As you can see, EPCOT has the highest differential between weekends and weekdays by far. MK is busier on Saturdays than Sundays. HS actually seems busier on Saturday and Monday compared to Sunday. With this in mind, if you have to pick two parks for the weekend and they need to be different parks, I would schedule as follows:
- Saturday: AK
- Sunday: HS
MK has the most attractions, so you may be ok going there on the weekend. EPCOT’s festival offerings are apparently diminished on weekdays, so factor that in as well.
