I am throwing an outdoor bridal shower in August for a friend, it will start at 5pm, she wants a cocktail party type shower. I am wondering if it is an absolute necessity to have a tent? The sun should not set that day until around 7:30. I plan to have candles on the tables, lights on my deck, paper bag luminaries. Should I rent a tent just in case it rains? It is an added expense of $300.00 and I know the bride does not wish for the bridesmaids to have to shell out a ton for this shower. Thanks for your help.
