So what I did was a playlist for every moment (seating, bridesmaid walk down, my walk down, cocktail hour, first dance and the dance party) and I had also written it all down just so no one would be confused lol. My brother said that he just had to queue up the songs and show the guy which ones to play and the guy took care of the rest. It didn't sound like my brother had to do anything and was able to enjoy his night. But I would prepare someone to be in charge of it just in case because Blanca did tell me that I would be 100% in charge of music. And yes the boat director announced everything for us (bride and groom entrance, first dance, dance, cake cutting, fire dancers, lanterns that we brought). They were so organized. I was blown away! If you need any song ideas I still have my list and can e-mail it to you if you want. Have fun planning!
