Congrats! I found that choosing a destination and a resort was the most stressful part. If it were my fiancé and I, it wouldn't matter as much if I chose a horrible resort, but the pressure of choosing for 40 people was crazy. I ended up relying on my TA a lot to give me recommendations and then once we narrowed it down to our top 3 resorts (all of which we would be happy with), it honestly came down to the price.
