My family took the alpaca world, nami island and the rail bike. The guide was Jordan and we found him really informative, kind and helpful. He helped take pictures at every stop and taught us a couple of Korean words to use. Importantly, the tour had a self-paid lunch but they brought us to a halal restaurant. The time shared between each attraction site was sufficient for us to enjoy and get a snippet. In a nutshell, we thoroughly enjoyed ourselves and really recommend this tour if you are thinking about it.
