Using から

[SnoWhite]

＿＿＿＿から、いきません。

Grammer-wise, what is wrong with りょこうがすきじゃないですから、いきません。

[KyleGoetz]

You typically don't use ます form anywhere in the sentence except the last verb, if even there.

旅行が好きじゃないから、行きません。

Granted, people do use ます form elsewhere for a formalish effect (or to sound like an idiot, depending on context: I'm looking at you, little pocket robot from Chobits), but I wouldn't worry about that at this stage in your learning.

I've tried that but it was also incorrect. Would it make sense if I have いくん in there somewhere?

[andylaurel]

Probably not, no.
Wait, what?

行くん　is a question in Gunma..

It's not so much grammar as the wrong word choices and combination. A native speaker would NEVER say this. The すきじゃないですから part sounds as foreign as something can sound. 　

Why combine the highly casual じゃ with the non-casual です or ません? The speaker must choose one way or the other.

Non-casual: 「りょこうはすきではないのでいきません。」　You don't need a comma in this.　

Casual: 「りょこうはすきじゃないのでいかない。」 More colloquially, 「りょこうはすきじゃないんでいかない。」
