How is the metro system during NYE? I'm living in bearing, will probably go to Central

Im not going to be using road transporation or the river, just using metro.

since im going to be on the green line, it will take me straight to central festival.  

I thought about iconsiam but it's going to be crazy going back due to having to use multiple modes of transport.

I am curious though, will everyone be able to fit in the metro going back home?   
Say 1-2am? It takes 1 hour to get back by metro.

 I already have a spectacular view of the city from where I'm at so I'm considering just staying here.
