Here is some good news that highway rest stop receipts can actually get you discounts at local tourist attractions.

If you present receipts obtained from highway rest stops during the Chuseok holiday, you can receive discounts at 56 local tourist attractions.

The discount rate varies depending on the destination.

Discounts of up to 60% are available.

There are various places where these discounts apply, including cable cars, observatories, and arboretums.

Since this does not apply to just any rest stop or any tourist destination, it would be a good idea to do a quick search and enjoy a rewarding trip.
