I stayed in a stand-alone suite on a busy bridge in Seoul. It was pricier than a 5-star hotel and noisy, but views of the river were stunning.

• I spent the night at Sky Suite Hangang Bridge, a glass-walled room suspended over Seoul's Han River.
• The panoramic views of South Korea's capital made this just-opened urban oddity a memorable experience.
• But at up to $365 a night during peak season, coupled with traffic noise, it's more about the novelty.

As I stood on South Korea's Hangang Bridge, cars whizzing by, I wondered: who thought putting a hotel suite here was a good idea?

I was about to find out.
