I had an outdoor wedding..2 pieces of advice:1) HAVE A BACKUP PLAN !!I had a Tropical Storm come through on my wedding day. We had to move inside2) HAVE A LAID-BACK WHATEVER HAPPENS HAPPENS ATTITUDE.No need to cry about something you can't fix.. AKA the weather. (it was still the best day of my life.)
What differentiates an average host and a great host is anticipating unexpressed needs and wants of their guests. Just because the want/need is not expressed, doesn't mean it wouldn't be appreciated.
