Rule Number 1: Everything in China "sounds a little dodgy" to those of us from developed countries. Everything.

I might be a tad biased since I lived there for a year and a half and was on a student's budget and therefore couldn't really always afford stuff that wasn't (and was priced at a high premium).

Call the folks at ctrip, they speak English very well, and figure it out. You'll be fine. Also, calls to China are no longer expensive. If you are worried about the cost, feel free to buy a calling card, which will make the call cost something like 2.5 cents/min or something.

Good luck and let us know how this turns out.
