Things I have learned:
1. My fiancé and I made the decision to not include anyone in our venue search, and it was absolutely the right choice for us. People seem to forget whose wedding this is, cough parents, and we didn't want any other opinions clouding or judgement.
2. If you are even later to the show then we were, chances are you are going to feel pressured to take a date even if you are not in love with the venue, before that too gets ripped away from you and you're left getting married in Aunt Mirdle's backyard, which could be beautiful also. Don't feel pressured to take a venue you don't love. Things will fall into place. And remember if you end up getting married on a Tuesday at a venue you do love, you could end up saving a lot of money. Plus the people you need there will be there, it might even be a convenient way to weed out people you don't.
3. My biggest advice is try, TRY, not to be overwhelmed. Planning a wedding is suppose to be fun, and hopefully you only do it once in your lifetime, so enjoy every long drive, overpriced venue, horrible minute of it!
