how do we get from baiyun airport to china hotel-mariott?

Upon landing, you can take airport shuttle bus line 5, get off at Dongfang Hotel first. It takes around an hour on the way. The ticket fare is CNY 17 per person. Then walk south around 200 yards to find the hotel.

Or you can take subway line 3 to Jiahe Wanggang Station first. Then transfer to line 2 to Yuexiu Park Station, Exit E. After arriving, walk northwest around 250 yards. The duration is about 40 mins. And it costs CNY 7 per person.

Thank you so much for this valuable information Judy. Do they allow 2 big luggages inside the bus or the shuttle? Or is it better to take a taxi and how much does it cost for 2 people?

Thank you so much

Yes, there are enough space to put your luggage. Don't worry.
Of course you can take a taxi from the airport to the hotel directly. The fare is CNY 80 to 90 per cab in the day time.

Thanks so much Judy for all the valuable information that you have given me. I really appreciate them and your time!
