Yeah I'm the same Jay, prefer to do it on my own usually... but have to admit I just came back from the second and by far the best experience I have had with a package tour in Beijing. Awesome, went with Dragon Air and took every hassle out of the whole thing. Especially if you only have a few days and don't speak Mandarin. Private guide and driver, most meals, great hotel, airfares and they mixed and matched the tour to our specifications too.
Even got upgraded to business class. Noice.
www.kaholidays.com is the website. Beijing rocks by the way, check out Coco Banana's, the Green-t-house and of course Great Wall, Forbidden City, Hutongs etc. Way better than most people had told me
I can recommend!
