Hello! Thank you for the honest review. I really appreciate your time to write the review. However, the tour price includes gas(fuel) so please don't get this wrong. We don't include any toll, parking fees, Meal including tour guide's lunch, entrance fees which is mentioned on the booking sites already.
The reason why we didn't include them are as follows.
Firstly, It is private customized tour. That means the clients can decide wherever they want to go or skip the places they don't want to go. Therefore we shouldn't include any entrance fees, parking fees and toll to make the tour more flexible.
Secondly, We can include all of the above with enough amount of budget but that means we have to maximize potential spend during the tour and also have to top up the service fees which you again have to pay extra to the platform.
I understand the most of the tourist don't want to pay the hidden cost but actually there's no hidden cost if you can read what is included on the price and what is not included.
Furthermore, regarding the overcharge, You mentioned that you wanted to visit all the UNESCO sites in Gyeongju and it takes usually 1 full day and another half day to visit all the sites. The overcharge is set by the Association of Korean tour guide which is 30,000KRW per hour to protect the environment and welfare for all the tour guides in Korea. I wish you could understand that. I already told you this before the tour began.
This tour cannot compare the price with a bus tour. I am sorry for this. Thank you and have a great day!
