It's located inside the terminal so there's no need to go through customs and immigration. It's also reasonably priced at $90 for 12 hours.
hmm? well, if the idea of spending the night in the terminal is appealing, then i suppose the transit hotel could be an option. but, given that the outdoors is oh so close and korean immigration is a breeze, i'd personally have a hard time justifying such for an overnight.
