I have always shipped my bike to the LBS because I trust there wrenching ability more that mine. If you have no concerns in that regard you may be better off shipping to a host or hotel as then you don't have to work around the bike shops hours.
Use either ShipBikes or BikeFlights for shipping. The rates they have negotiated are a fraction of what you will pay at the window. They will also provide you w/ all the proper paperwork. Also note that there is a maximum size for your package for international shipping before it falls into another, more expensive, category (sorry, can't remember the dimensions). Depending on how big your bike is it may require quite a bit of dis-assembly to fit in a box that size.
That's what I got.
