Travel

I think I'm not alone when I say that I like to travel. isn't it? It is one of the best things of in life. I would need to have a lot of money for to travel around the world. I love to known about another cultures, beautiful places and people, so , I'd like to a little taste all about of some others countries.
Let me tell them you a one secret: I'm going to save some money , but, I'll start it tomorow!!!! lol

I love to travel too! I don't get enough opportunity though!

If you would like to use "isn't it" it needs to come after a statement for which you are seeking affirmation. For example "It's hot isn't it?" You know it's hot but you want your friend to agree with you.

More examples

This food is delicious isn't it? (you think the food is delicious, you want your friend to agree)

It's a good book isnt it? (you think it's a good book, you want your friend to agree)

Notice that you can only use isn't it when the word IS (it is/it's) is in the sentence.

I hope that helps!
