Usually not a problem getting on KTX without a seat reservation. You can walk up to the ticket counter and request seats. Seats sell out only during major holidays. Only on certain routes such as Seoul-Jinju will KTX tickets can sometimes sell out for high demand times such as Friday and Sunday. It will not be very complicated to purchase tickets. Basic english will be enough. There is also a ticket vending machine that has menus in english.


Yes it is possible. I defer to mikesaidyes post from 2014. I might add that it would probably be a good idea to contact the hotel in Gwangju ahead of time to let them know of luggage being delivered to them. Or have the hotel in Seoul contact the hotel in Gwangju to give them a heads up.

I'm not sure if lockers are available for overnight storage at Busan station. Also there are not many large size lockers and they tend to be filled. One option you might consider is storing your luggage at Busan/Gimhae airport. They have luggage storage there and you can leave it for a few days. Also, there is a bus service from Busan/Gimhae airport to Gyeongju. Downside is that the airport is a bit outside of Busan. You can take the metro there, but with a few transfers.

It is pretty easy. Large suitcases are stored underneath in the luggage compartment. But the issue is just navigating and walking around with large luggage. Uneven sidewalks, curbs, escalators etc.
