Boat Fly around

Hi, I need some advice regarding our new Archviz scene.

We have setup a scene with a boat in the sea. The user is able to walk on the exterior of the boat then the user will trigger an event at the end of boat and be taken a distance away from the boat and have a fly around to see what the boat looks like from a distance. The user will follow a given path around the boat in the air and while they are moving around the boat they will be able to move their view with WASD keys to look around.This project will be packaged as an HTML project as well.

What is the best way to do this using Blueprints? Please also note my Blueprint skills are rudimentary at best.

Any help would be great, thanks.
