Hey! Michael, welcome to China. I live in Beijing and travel a lot every year, either business or just sightseeing.
The garden located in Yangshuo county of Guilin city of Guangxi province. The small garden just opposite the West street where is very famous in Yangshuo, everyone must know it, and I suppose you will surely love the street as soon as you arrive there. West street is perfect combination of ancient and morden. There are many nice bars and restaurents. I suggest you and your honey should stay in there a few days. Both of you can ride bike through original village, and take a boat to watch unique scenics, or taste delicious local food, then, go back to stay in small family hotel with good price as value.
Further question let me know.
