WeddingWire was the main resource we used when planning our wedding and the tools were amazing. First of all, they have the easiest to use and most modern wedding websites available. Many other sites offer dated website templates that are hard to pull up on your phone.
We also really loved the budgeting and seating chart tools. We are both incredibly visual and these tools helped us stay organized. I would recommend the site to anyone who is looking for one place to keep all of their wedding details organized.
