When should I book my vendors?
As a photographer, I recommend you don't wait on booking. I've heard of couples booking more than a year away. Not only will early booking help ensure you acquire the vendors you want, but it will also reduce much of the stress leading up to the wedding. It's rare for a wedding to go 100% as planned, so the earlier you handle the more time intensive tasks (such as booking) the more time you'll have for creating backup plans and enjoying your last days together unmarried.
