How do you choose? Three questions
Landing after midnight?Trains stop around 24:00. Your options are the night limousine bus (limited routes) or a taxi — and for two or more people splitting a taxi, the math gets reasonable fast.
More than one big suitcase each? Take the limousine bus. It drops at major hotels, the driver loads your bags, and you skip the subway transfer that turns the cheap train into a sweaty regret.
Hotel in Hongdae or near a Line 2 transfer?The all-stop AREX is genuinely the best option, not just the cheapest — Hongik University station is on the line, no transfer needed.
