Because doing it at home is both more expensive and no fun for you!
Share the Space
Many grads have their party on the same day, so they cannot visit each other.
Sharing the space allows them to be together, and allows your guests (often the same people, other than close relatives) to spend more time
Share the Food
Glenhaven can host 6 - 8 grads at the same time, and thus you can save money on setup and on food.
Share the Cost
A graduation at Glenhaven costs $1000 per student, and no more than $4000. As such, if you gather a number of students, you can all share the cost, and save money, time, and stress, while greatly enjoying this special day.
