Is this the right kind of spanish for me?

I found this site and I'm so excited to order it! But before I do, is this Spanish more based from Spain? My fiance is from Mexico, so I'm trying to learn Spanish that he will understand? Is this the right product for me?

Hi, Katy. Welcome to the forum. The Spanish you'll hear in Rocket Spanish is what you'll hear throughout Latin America rather than the Castillian form used in Spain.

Hola, Is Spanish from Mexico much different from Spanish from Puerto Rico? I would think they are much closer than Castilian Spanish? I saw that someone compared Castilian Spanish to Mexican Spanish as England is to United States English. Thank you, Knezz
