I’ve done EMM from Poly several times.
Since they let you in the MK gates at 7:45am’ish, I try to time it so I’m at the MK, checked-in/waiting by 7:30’ish.
My first choice of transportation is Monorail. The Resort line ‘usually’ starts running at 7am. Check the Times Guide when there just to be sure, here’s a helpful link as well:

So we’ll usually leave our room 7am’ish to make our way to the Grand Ceremonial House/monorail station. You’ll go through security prior to getting to the monorail station platform. Some may prefer to build in more fudge time there, I’ve generally been ok hoping everything goes well.
If at all worried or your travel party moves slowly ,time it so you’re at the platform at 7’am’ish.
I don’t trust the resort boat that early. I’ve stayed at Poly more times than I should admit and I couldn’t give you a definitive answer as to what time it starts running. It may be running early enough for EMM but it may not, so I like the other options.
With the monorail, it’s not a bad idea to have a Plan B (or C or D) involved “just in case.” When the monorail isn’t running, there is “supposed” to be a bus to MK - but that can be a stressful proposition when you have an expensive event that you need to get to on the line.
So, my Plan B is to get a cab to CR then walk over (sounds crazy but I had to do this once).
My Plan C is the Resort boat if I see one running.
My Plan D is walking to the TTC and taking the MK Ferry.
95% chance you’ll be fine with the monorail, I only mention the others just to have options in your pocket if stuff happens.
As to parking at Poly on your check-in day, you’re all good - nothing to worry about.
Hope that helps, and happy to answer any questions/clarify anything.
Mini Rant! Where are park hours, Disney. What happened to MK late hours on Wednesdays? Is Jiko going the way of Artist Pont with no reservations available after June 30th?
