is a free charter bus that take off like every 30 minutes from multiple stops downtown. Also recommend like others riding bikes in Stanley Park. Definitely get an ebike and you can get through the park with stops within 2 hours. We used https://www.jo-e-cycles.com/

We were there in December and stayed at the Marriott right downtown by the waterfront, and didn't encounter any zombies there, but found them further down towards the Gastown area.

Have fun, loved the city.
