Hotels on harbor and conflict with parking end time

I booked a good neighbor hotel on harbor across street from entrance to parks, but have been told by hotel that on check out day, we can only park til 3pm. We want to stay at parks til 10pm on our check out day… So do I have any other option rather than having to leave park to get car and move it to disney lot and pay parking fee there? Doesn’t that just negate the whole reason for staying within walking distance. How have others handled this?
