Planning what could be the happiest day of your life requires creative input from both partners and any family members and friends you've decided to include in the planning, and also rigorous preparations to make sure the day goes smoothly. Wedding planning can be a wonderful part of life but it can also be very challenging and stressful. Indeed, you can be assured that some plans won't go as you'd like them to, so plan for that eventuality too! The key is to stay organized, to stick to a budget and to give yourself plenty of time to achieve everything.
