Alchol before IVF treatment

My husband has planned a surprise trip to Dublin for the weekend for my birthday. Our IVF treatment starts 12 weeks from now, 10 weeks after our trip. I've read my notes from the hospital that say I need to avoid drinking alcohol - which I have completely for the past 4 weeks and planned on sticking to until he told me about this trip. Will a weekend of drinking 10 weeks before IVF have any effect of its success? Does anyone have any experience of this?
