But.. nature happens, it happens to everybody at some point. It seems that in New England, nature happens a lot! If I could do it all over again, I'd get married (to the same woman) indoors. Actually, our wedding was inside, but thank goodness it was, because central NH was flooded on that October weekend! (Like, National-Guard-and-detours-flooded!)
Weather can happen to you. It could, potentially, derail your day! So, you must have a contingency plan:
1. Full coverage for your guests. No, they can't have their seats at the edge of the tent. You need a big big tent. Your guests will leave as soon as they are uncomfortable.
2. Full coverage for your DJ & musicians. No, they can't have their cables, table, laptops and lights on the edge of the tent. What you need is a big big tent! Your music people won't run their gear if there is a chance of it getting wet. They may, in fact, demand their balance and go home early!
3. Safe electrical. Plugs run from dry spaces into a dry space. No, they can't be connected on the wet lawn. What you need is a huge big tent, with professionally run power. Don't put stuff (tables, chairs, vendor stuff) near the edges of the tent. It helps to have a big big tent. (Like really big) . I'll just leave this word: "Electrocution" right here
4. Beyond adequate bathroom planning. Roads wash out, and your guests can be stuck later than planned. Double your bathroom planning. 4 bathrooms adequate for 100 people? Nope, get 8. And put lights in them! Better yet, get trailer bathrooms. Those don't tip over and you stay all the way dry in them.
5. Towels. Your guests, staff, and vendors need them. Keep them dry inside a big tent. (think really really big when you think big tent)
6. Staff. You need staff to keep the dance floor dry, raise and lower tent sides, and arrange for evacuation if a big storm comes in. No you are not safe in a tent in NH. Check this link out.
7. Experienced Vendors whose service experience is based in reality. At some point, because of the weather, plans must be changed for the sake of safety and if possible, comfort too. Do not expect great pictures in misty rainy conditions. Do not expect any music when the power fails. Campfires suck in the rain. (Waste of time) Think you know the business better than your bartender, officiant or photographer? Think again! They'll be the first to tell you, get a bigger tent next time...
