Split stay and an ECV

We are renting an ECV for our next trip 11/29-12/9. What time do the buses start from POP to Disney Springs and then to Wilderness Lodge. We are planning on going to Kennedy Space Center on the move day 12/4. Renting a car and leaving early. Can we move the ECV early enough to WL or do I have to leave it at POP and pick it up later? Can split the ECV rental but would lose the 10% discount.

Some ECV can be put in a trunk you might need it for KSC. All so someone posted that there might be a bus that goes to KSC so you might be able to kill two birds with one stone.

Sorry that I did not answer the question asked but it might be food for thought.
