Which train from Narita airport to Shinjuku???????more then 1?

Question:

Flying from Gold Coast to Tokyo for a holiday I will be ready to leave Narita airport to get to Shinjuku at the Ace Inn backpackers (５-２ Katamachi Shinjuku)

If any one could please help me figure out what train to catch and if I have to get more then one I will really appreciate it.

Answer:

There are actually 3 train services available at Narita Airport.
1). JR Narita Express
2). JR Sobu
3). Keisei Skyliner
Spunkiee is sure that JR Narita express go directly to Shinjuku & Shibuya
The other 2 will lead to Tokyo and you have to change trains to get to Shinjuku.
