Hola Melvin

In Spanish, the verb forms "va" or "van" depend on the subject they refer to. In this case, "va a disfrutar" is used with "la gente" as the subject, which, despite referring to a group of people, is treated as a singular noun, hence the use of "va" in singular form.

It's a common feature in Spanish to use singular verb forms with collective nouns when considering the group as a single entity. However, if referring explicitly to multiple individuals with a clear emphasis on their plurality, for example, "las personas", "van" would be appropriate. So, "la gente va a disfrutar" is correct when talking about people in a general, collective sense.
