I agree with @@krisdaversa. They are not necessary. It just depends on whether you want them or not. If you don't plan on doing anything with them then whats the point! But you have to go with what's important for you and if by not having them taken and it allows you to spend more on your wedding photographer or videographer, then that might be a better use of your funds. I did have engagement photos, however, we did them while on a trip to Croatia. I absolutely love them and am soooooo happy we did them, but I think it was more so because they are very special for us as they also document a fantastic trip that we went on together shortly after our engagement. I do not think I would have had them done though if we were just doing them at home. We ended up creating a photobook guest book with our photos and we used one of them on our Thank You for Booking Postcards... I will hopefully eventually get a few favourites printed off and put them up around the house.
