Tents are not really important... Until starts raining... then your guests and family will start running back and forth to help you cover everything that is getting wet (decorations, food, chocolate fountain, linnens, etc) trying to save a party that went to coma. Lets face it: You can not take control over the weather. We neither. So it is not just smart getting a tent for your next party. It's beautiful! Just take a look at this pictures:
