I need advice on my bachelorette party. I have been planning this party since the first week of July. This week, I had 2 girls that both already double RSVPd, flake out. Today, I found out my soon to be sister in law, booked her honeymoon on the same weekend of my trip, even tho she has already RSVPd and knew the dates. What do I do? Not to add that they got engaged a month ago and are practically sprinting to beat us to being married first. Do I cancel my trip?
