Thanks the information.

I have found that my flights use Terminal 3. Is the BRT possible from there? Again, because I cannot see the BRT and metro lines on Google Maps (unlike, say, London etc.) I find it uncertain where the stops and lines are. Any useful help on that would be great.

As mentioned, my hotel in near Bailuzhou Park.

I do want to visit Gulangyu for a day, so your tips about the ferry terminals for locals and visitors is useful.^
