my parents, as well as mr. smithers, are going on a cruise to alaska next summer.

Explanation:

When using "as well as" to connect two subjects, the verb agrees with the main subject (the one before "as well as"). Here, the main subject is "My parents" (plural), so the verb "are" is correct. There's no subject - verb agreement error.

Answer:

There are no errors in subject - verb agreement. The sentence "My parents, as well as Mr. Smithers, are going on a cruise to Alaska next summer." is correct as it is.
