Same thing happened to me, but it would have been a 4 hour plane flight. I decided against going. Even though it turned out that I did not have the baby that weekend, I was SO HUGE by that point that attending would have been totally exhausting. Let's face it, at that point you can't dance, you can't eat much of anything, you can't drink, you have to pee every 2 minutes, your feet are swollen, people take to asking you, "Wow, are you having twins? You're HUGE!" Better to hunker down at home, in my opinion. ;) Your friend will understand.
