Structure of sentence with 喜欢+V
Maybe a comparison to English will help you remember:
我喜欢坐飞机去。(adverbial)
I like to travel by plane.
我喜欢坐飞机看风景。(still adverbial)
I like to watch scenery by plane.
However:
我喜欢坐飞机（，而不是坐火车）。(followed by nothing)
I like to take planes(, not trains).
I'm not sure if my explanation makes sense. Just for reference.
