transport from Beijing capital airport at night

You plan will land in the airport at 11pm?
I am not sure you can catch the last bus line 3 at 24:00.
I think you can do as follow. If you can catch the line 3, you can take this line to Chaoyangmen Station and change a taxi to your hotel.
If you cannot take this line, you can take the shuttle bus line 2 night line to reach Chaoyangmen Station and then change a taxi to your hotel.
