Sandy:

Thank you for your message.  Our trip was fabulous, and we could not have been happier with the tour, the guides, the hotels, the food and the service provided by your company.  You can be sure that we will be recommending you to all of our friends who might want to visit China.  I will be happy to serve as a positive reference when necessary, and will send you some photos as soon as I have had time to sort them out.  When we plan another trip to your part of the world, I will contact you and hope to get to Guilin.

Warm regards,

Deborah
