Test previously ; it can be so simple as moving the tables around a corner, or across the park to a more sheltered area. I recall an amateur marriage video where the majority of the sound was the wind whistling around.

Cheap wedding centerpieces. However, you have to limit the things you have got to fret about if you are going to enjoy yourself. A party in a park by a lake would be nice, or by the pool at your aunt's mansion, or maybe at the beach, but in actuality, if there are going to be kids there, and drinking there's also going to be the possibility for a genuine crisis. Ice cream will not do when it's ninety degrees outside, nor will hot hors d'eouvres last long when it's fifty degrees outside.
