Sounds like you are determined to go despite the risks. Well, it's your decision.
I once won a trip involving a factory visit in the states followed by a week in Hawaii. I was about five years sober as I recall, and the trip was awarded by my employer. I thought about the nature of the trip, how busy, how tired, I would be, and ended up asking my boss to give it to a workmate.
My sobriety has to always come first.
