The Hump Day Poll

Let's say you are hosting a NYE party. You've been actively recruiting people to attend, sending out E-vites, the whole nine yards. You already have between 5-10 people who are attending. Then, a mere three days before said party is to commence, you cancel the party, because you somehow acquired tickets to a NYE bash at a semi-swank, downtown hotel. OK readers, what do you think:

1.  Hey, it was their party to do with as they please.  Good for them!
2.  Sounds kind of lame but hey, it was their party.
3.  No opinion really
4.  Totally classless move, they should be ashamed
5.  Horrific breach of social ettiquette, a complete loser move, should have future social ramifications.

Discuss.
