Convocation Extra Guest Policy?

Hi everyone!

I will be graduating in October and just found out that my parents planned a surprise party for me with 6 of my extended family members flying out from England to come to watch me graduate. As excited as I am to celebrate with them my parents did not know that we are limited to 4 guests per graduate.

Since there are no tickets required for guests anymore is there a way that everyone will be able to make it or will I have to deliver some bad/awkward news?

Any advice to get out of this awkward situation and not upset anyone would be greatly appreciated.

Thank you!
