Great do it yourself tour - Great way to get to know the city and visit so many landmarks. You can tour the different areas at your own pace.

Would go back to see the rest of Korea - Seeing Seoul's beautiful landmark, we’re able to cover at least 5 out of 14. My only complaint I wished the bus drivers are more accommodating to non Korean speaking visitors, one driver is really rude to me and my daughter.

Alright for the price but not great - Like the other reviews have mentioned, this is better treated as a bus that takes you to places you want to go, rather than a “tour bus”. Also will need to navigate your own way to some spots from the bus stops as they often don’t drop you off right at the sights. For the price, no complaints, and if you’re short on time and just want to ride the loop to see the city, it’s not so bad either. Buses came punctually but 40 minutes is a lot of time between buses - wish they’d increase their frequency to every 15-20 minutes especially given the buses only run for about 7 hours a day. You’ll lose out if you try to “hop off” to see everything. Wish they offered a route that covered more ground (ie Gangnam, Itaewon) or added them to the existing route. Would be more convenient if the voucher sufficed to board at any stop instead of having to go to Gwanghwamun Station to redeem for a ticket.

Not good - It is better if you do the city tour. This tour just goes around the city. It's like taking the bus. Goes around important points.

Very Disappointing - Stop is hard to find as we were not told which station exit. Bus we had was not easy to see out of by design plus windows were filthy. We were trying to listen to the recording but lady/ or speakers was blaring the Korean version while we were trying to hear English.

Disappointing Experience - It was not a recommendable experience. You can just go to places by bus or subway without any problem. It was just one ride in total. The bus took so long time to arrive to each place if you don't like the place or have visited it already. The other Hop On and Hop Off experiences we had (from other countries) were not like this, there were available bus that roams around the city that we can access anytime.

No added value - The Tickets from VIATOR have zero added value, are more expensive, and no documentation what so ever was received. Ifyou book directly by the bus you receive a map with stopping placed etc. The tour itself is great and shows a lot of highlights from Seoul

Wasted the whole day waiting.... - It's the worst hop on hop off that I've experienced. The interval of the bus is too long that if you stop at a tourist spot and you feel like that u don't like it you don't have a way to go to the next site coz you have to wait for 40 mins for the next bus. If you ask me just use the public bus instead. Its cheaper to get to the sites you want to go and the next bus is available every 5 to 10 minutes.

Don’t Do It! - What a waste of money! We ran to make the first bus only to find out that the stop had changed due to the Seoul marathon. Not a big deal but we were not informed (was it that hard to send an email out to registrants?) We ended up missing the bus and having to wait 40 minutes. Also, they informed us that two of the stops were not available that day. The English translation was awful with barely any information and every bus was way over booked. I take a hop on/hop off style tour whenever I am in a city for a short time. This was the worst one I have ever taken.

Just a bus with a second floor - Terrible, only in Korean and the double decker bus had a roof; for that do yourself a favor and buy a regular bus ticket and stay on it for an hour and a half same basic experience only youre paying far less and can get off anytime. I took a cab to my destination that was more entertaining
