If Staying half the nights on resort extra hours

Ok so the trip I’m planing for disney has 5 nights that are $50 more then the other 3 nights.
So I have a question about how extra magic hours work.
I know day of arrival and day of leaving you can use extra magic hours.
But say I stay onsite for 3 nights then offsite for 3 then back for 2.
So the day I switch to the other hotel and the day I come back should be covered by extra magic hours I’d assume.
But what about the day in the middle. Would I not be able to go to extra hours on that day?
Or is disney more slack on this?

That one day in the middle you would not be able to do EMH. Check out day and check in day are covered. There is no slack. It’s a rule and an important one.
