I will have the pleasure of driving my family around Korea for ~4 days in November so I need to rent a minivan. There are 6 of us total so a normal minivan will do but I plan on driving all of us from ICN to a town 2.5 hrs away from Seoul so may want a larger van, like a 9-passenger one, to accommodate for the luggage.

The best deal I see is on Sixt in Gangnam at around $100 per day for a 7-passenger minivan. Anyone know where I might be able to find a 9+ passenger van for rental at either ICN, Seoul, or anywhere in between? I can read Korean, navigate through Korean websites, but don't have access to Korean bank or credit cards.

Thanks!
