Final answer:
The Montagues plan on disguising themselves as servants.
Step-by-step explanation:
The Montagues plan on disguising themselves as servants in order to get into the Capulets' feast. In Act I, Scene V of William Shakespeare's play Romeo and Juliet, Romeo, who is a Montague, attends the Capulets' feast after he and his friends Mercutio and Benvolio disguise themselves as servants. This plan allows the Montagues to gain entry to the feast without being recognized as members of the rival family.
