I don't just suggest getting a tent for your outdoor backyard wedding, I practically require it.
Yes, it might not rain, yes it might be the perfect 74 degree day with a low UV and no humidity.
BUT if you live anywhere outside of southern California where inclement weather is unpredictable and unenjoyable for long amounts of time, you want to be PREPARED.
I like my clients to book a tent + a restroom trailer FIRST. Since these are non-negotiable must haves, this will easily set the tone for your guest count and the other extras you want at your wedding, like flowers, catering, cake and entertainment.
But mostly guest count.
I've said it a million times but the best way to keep costs lower is to keep the guest count lower. And no, I am not your wedding Scrooge. Just a little dose of tough love.
WHAT IF MY DINNER ISN'T A SIT DOWN?
Do you need tables and chairs? YES but not as many. You still want guests to have the opportunity to mingle to eat while not standing, to rest. Have enough for at least 1/3 of your guests but supplement with high tops so people have a gathering space that they can set their drinks down on.
IN A PERFECT WORLD
There would be a security manned coat check for the ladies to put their purses. A charging station with cords so guests can easily re-up their batteries. There'd be a restroom trailer and not biffies. You'd have misters if it was too hot and a fan; you'd have heaters and blankets if it was too chilly.
Butler passed apps are a dynamite idea, and self serve drinking stations INCLUDING WATER will make guests so so happy.
