Hello how may I help you? I need some help planning my wedding ok. I can help with that. I would like to know if a beach wedding or a private island wedding would be more expensive There are many conditions and variables that determine the cost of a wedding, so its impossible to say which will cost more. wow really. Yes thats weird I thought for sure the Island would cost more Just because its on an Island, doesnt mean the other costs are the same. If i rent the whole island vs just a beach? What if the island is full of rats. Do you think the cost will be as high?
