WE (I & MY HUSBAND AND 2 KIDS) WILL VISIT BEIJING FROM 10TH SEPT UNTIL 13TH SEPT. AS WE ONLY HAVE 4 DAYS IN BEIJING AND OUR SCHEDULE IS VERY TIGHT, CAN YOU FIND A TOUR GUIDE FOR KIDS IN THE PARK AND IS THERE ANY EXPRESS PASS TO THE GAME (LIKE EXPRESS PASS IN UNIVERSAL STUDIO IN SINGAPORE)?. WE WANT TO VISIT SHIJINGSHAN AMUSEMENT PARK, BEIJING HAPPY VALLEY AND BEIJING AMUSEMENT PARK.
