Didn't get o the Gray Line Tour due to numbers but the Boutique tour was great.
The tour driver has a good knowledge about Australia and a good sense of humour to make his narrative interesting. He's a good and careful driver. Overall I had a good time with your tour.
Despite advice on website regarding Korean Communications during the tour, this was the only opportunity I had to see the Blue Mountains before flying home. I was the only English speaking tourist (with 50 Koreans), however, everyone was very friendly and courteous, including the driver and guide - i have rated it as one of my best days out since i came on holiday to Sydney 3 weeks ago. The amount of free time in each attraction was just enough, without getting bored, allowing more attractions to be seen on one whole day trip. I must however, absolutely congratulate the Tour Guide whom, from the moment i stepped onboard looked out for me and made sure i was okay as i was solely the only English speaking person there, advising me on times and where we go next and what to expect - he was brilliant, friendly and 10/10! Please pass on my thanks to him. I had a great day, i truly did!
