There are two ways to reach the conference hotels. You may hire a limousine at L1 and L2. Each rental can hold 4 passengers. So, if you can coordinate your ride with other RSM participants, you might have some savings there. Print the following directions for the hotel you are staying before your trip, and show it to the desk clerk and the driver.
Chinese translation is provided in the direction.
You may want to keep this during the entire course of the workshop, in case you don't know how to get back to the hotel after your venture. Talk to the driver on the way to your hotel. If you both can communicate well, ask for a business card from the driver to arrange a return. He can come to your hotel to take you to the airport after the workshop. Of course, don't forget to ask for a receipt.
