By far the worst experience I've ever had while traveling, avoid at all costs. I had a 16 hour layover on my way home from travels, organized a layover tour to get picked up from airport to the great wall and back, with plenty of time in between. Arrived into the airport at 1:30 AM and no one was at the VISA counter, was unaware once you pass that area there is actually NO way back. I entered the airport, looked for assistance on how to leave at 7AM for my trip, was instructed to go a certain route, talked to a few people, until I was instructed to go up in which looked to be an employee only entrance. At this point I asked for help from a security guard who proceeded to laugh at me through a locked gate and then turn around after a minute of me trying to ask, where do I go or can you help me anything? He laughed and ignored me, until a lady helped me after 10 minutes, asked her manager if I can proceed into the country, denied the fact that there was no one at the visa counter (even though I asked why would they deny a tourist trying to spend money and learn and experience their culture) but never again.
