I am sorry about the late response, but after returning from China it was quite hectic on our side...
We did have a nice trip and we enjoyed it a lot. Thank you very much for all your organization and advices. We never had to wait for a guide, they were all in time. The hotels were also very convenient and clean, we can recommend all of them.
Concerning our itinerary we would suggest to add the following sights: on the way from Chengdu to Emeishan we asked the guide to bring us to Jianjiang to see the 1000 Buddhas. Although we were a bit too late to enter the temple with the 1000 buddhas we enjoyed the scenery and the rocks with some carved buddhas a lot.
The dinosaur museum in Zigong was very interesting (none of the travel guide books list this unique museum) and also the one about the salt dwelling. It would have been nice to stop at a salt dwelling still in use, but unfortunately we only passed by.
We will definitely travel again to China since there are still many interesting parts left for visiting - maybe in 2004. In any case we will then contact you again.
Looking forward to using your agency again.
