Hello everyone. We are a couple and a 7 year old kid. We are visiting Sydney for couple of days in mid January. We were planning to get a My Multi Day pass for 2 days. We would use the pass to visit Blue Mountains early morning. After getting off at Katoomba, I have found we have two options. Either take the HOHO bus tours or the public bus service (which is covered by the My Multi Day Pass). There are plenty of recommendations for the explorer bus but comparatively less discussion about the public bus. Since we are only interested in Scenic World and Echo point (we have to get back to Sydney for a 7pm Opera show), is public bus a good option? The route 686 seems to cover both these points with half hourly buses in morning and every 15 minutes noon onwards. Would this bus be a reliable option as it saves time as well would be free to use also? Or should I consider the HOHO bus, which operates on the full tourist circuit and may be possibly squeeze in something else to experience before departing to Sydney. Thanks.
