That's interesting, I can see that being the case. Personally, out of the last 5 trips, we've started on Saturday twice and Wednesday 3 times. Wednesday to Wednesday used to be our thing. I changed jobs in between and can't take 6 days off of work now, but Sat to Sat works great.
We used to Resort Hop on arrival day then started in AK on our first park day.
Since COVID makes resort hopping harder, we've just been going into EPCOT casually on arrival day since we stay at CBR and hop on the Skyliner.
