We found Sunny just as you did on Trip Advisor and I am happy we did. My wife and two children (5 and 9) were in Shanghai in June 2013 for four nights. We utilized Sunny's service for two days. Sunny was great. Keeping in mind we had two children with us, she tailored our tour with things we could find interesting as well as our boys. She was prompt and made great suggestions. She was especially great with my 5 year old who can be a bit of a challenge from time to time. All in all, I would highly recommend Sunny.
