This depends on what you mean by a cultural experience.
If you were a visitor to the United States, simply going to an amusement park would be a cultural experience. This would be because you would be getting a look at a type of entertainment that is very typically American. It is typical of American popular culture. Looked at that way, Busch Gardens would be a cultural experience.
If you are thinking about culture more in terms of the arts, there are also aspects of Busch Gardens that are cultural. For example, there are shows there that can be seen as cultural. These include shows having to do with Motown music and with ballroom dancing. Both of these could be seen as cultural in the sense of being experiences that expose a person to the arts.
