<human>: Can you provide a brief overview of the text?

A couple months ago, my girlfriend (of 2+ years), our friends, and I had planned a big camping trip. Last month, she found out that her dad's retirement party for the Navy (held on the USS Constitution) was the same weekend we had been planning to go. I managed to find new reservations for the campsite for a different week, but a good friend of mine had already bought plane tickets (Chicago to Boston) for him and his girlfriend to come camping for the weekend. He's pretty determined to get camping in, and will probably go regardless of my decision. 

The party is Saturday night, so I could leave very early Sunday night and be with them Sunday-Monday, but it's a 5 hour drive each way. Do I miss seeing my friend altogether and go to the party, or skip the party and go camping?
