Alchohol for a party?

I have a house party tomorow, and I need some alchohol to bring. I dont want to share my alchohol accept for 2 friends. We want to buy a slab (24 bottles/cans) of beer, however people will see us with the beer and will try and make us share. How can I get smashed at this party without sharing my beer? And we not going to drink 24 cans before i get to the party.
