This is my first time "to / in" ...

Hi,

- This is my first time to a place.
- This is my first time in a place.
Do these two mean the same?

Here's an example of "This is my first time to ...":

And here's an example of "This is my first time in ...":

This is my first time in Korea.

This is my first time in/at Disneyland.
This is my first time in Korea.

If you want to use "to", you'd need to say "This is the first time I have been to Disneyland/Korea"

I agree with ems's answer. The child's 'to' in that clip sounded odd to me. I'll be interested to see what our AmE speakers have to say.

The kid was young enough to retain some semantic oddities of the kind that children are prone to have. It sure didn't sound natural to my AmE ears, even on the lips of an American.
