We have just booked our venue a lovely woodland venue and we can do with it what we like. We are about to pay the deposit on some tipis so I am looking at wedding insurance. It looks like you have to pay a premium for additional marquee cover. I was wondering what other people that have booked a tipi wedding have, did you pay the additional marquee cover? Thank you in advance
