Lizajane, as I see it it's the case of:
"Easy choices - hard life, hard choices - easy life".
To go there and hope that your newly born sobriety go through this ordeal would be an easy choice. But it can give you a hard life later. Though this event seems to be of ultimate importance at the moment, it puts in danger the bigger picture of living a healthy sober life and enjoying hundreds of events later without putting your sobriety in jeopardy.
It's for you to decide, of course. But from my own experience I can tell that no event is big and important enough to jeopardize the overall quality of your life.
Nine days is great but way too early to run it through a tough test.
Keep in mind that sitting in front of computer and and being in environment when everyone is drinking and having fun are two totally different things. Emotions will get under your skin. It will take a split second for a thought "Eff it, it's just one drink. I will start over tomorrow" to trigger avalanche of drinking and remorse.
Tough choices, easy life.
