I have never had issues with taking the internal bus at FW, but some people seem to dread it. As another option on the taxi, you could also take the taxi to WL. Then take the bus from WL to FW. Even if you have to wait for the bus, it is not a busy bus so you should have no trouble getting both scooters on the bus and it should only take a few minutes to get between the resorts. You could also walk from WL to FW, but depending on the time, it might be too dark out.
