The Senior Party is a fun and important Interlake tradition. It’s an ALL-NIGHT party that happens the night of our students’ graduation ceremony in June. The Senior Graduation Party gives our kids a special celebration event full of wonderful memories plus a safe place to party with friends and class-mates. Why risk celebration options that won’t ensure your student’s safety?

Event Date:     June 16th

Time:               TBD

Embarkment Location:           Interlake High School

Where is the party? Party locations change every year and are a BIG SECRET. Students won’t know where they’re going until the bus arrives at their destination. Rest assured that each location is a secure, drug and alcohol free environment with lots of food, music, entertainment, games and much more…all night long!

Tickets: Sale Price Rate – $210 + $5 surcharge for online purchases only (Sale price tickets available NOW -April 5th.)

Limited number of tickets are available. Purchase your student’s ticket NOW to reserve a spot. Registration is complete upon receipt of forms.

Scholarships are available upon request. Submit a completed application to your counselor by TBD. Scholarship application deadline: TBD. Scholarship eligibility are awarded on a first come/first serve basis.

What else do I need to know? TICKETS ARE NON-REFUNDABLE

Because this party requires a lot of volunteer time, energy and significant financial commitments, tickets are non-refundable. In the event you can’t attend, tickets may be transferred or donated to another Interlake Senior prior to June 11th. Email us at
