I want to go from international guangzhou airport to euro asia hotel, 186-188 xianlie dong road ?

You can take the airport shuttle bus line 2A and get off at Holiday Inn. Then you can take a taxi to your hotel, about 1.5 miles far. The bus fare is CNY18 and it takes about 80 mins. The taxi fare is about CNY10.
It’s hard to tell what time you should transfer, for the bus speed may be affected by the traffic jam. When you get off, just take a taxi. Don’t worry about that.
