2. I will guide you round today.

Are they all the same?

=======================
Does #1 mean #4, 5, or 6?

4. I will guide you here and there today.

5. I will guide you to many different places today.

6. I will guide you in many different places today.

#1 is best choice. (#3 maybe in Britain)

#5 is best match for meaning.

#4 implies a lack of specific intent or destination.

#6 is just bad usage.
