went with Lao air to Guangzhou last week with a plan to catch the through train to kowloon and spend a few days there before returning to guangzhou, GZ is absolutely massive and not all that interesting but what we saw of it, it was ok
First thing you notice is the smog
We were staying in the Holiday inn shifu in the Liwan area that was bang smack in one of the shopping areas
at $120 a night it was quite roomy
