Question: So, these two both mean 'to participate in' and there doesn't seem to be any difference in the types of things one might participate in.
Are they therefore interchangeable?
Thanks!

P.s. I am categorising my 'what are the difference' questions under 'vocabulary'. As they are all HSK 5 verbs, should I open a new HSK5 tag? What do you reckon?

Answer: 
Try a slightly different expression:  

I don't like travelling **that** much.
"我不是太喜欢旅游" does mean you dislike travel

If you don't want to use 'dislike' to describe your feeling on traveling, you can say: "**I am not too keen on traveling**" (我不太热衷于旅行)
