Activity for Nicole

When should I book the hair and make up artist? I feel like if I start doing trials too soon, my taste might change by the time of the wedding! My wedding is September 9th. I am afraid if I wait too long to pick someone that they won't be available....

Does the Wedding Wire wedding website allow you to have people RSVP online? If so, what is it like? Can I enter the names, # of guests, meal selections, etc. myself? HELP!
