I'm getting married on the beach in May and the place where I'm having my wedding only supplys 30 chairs. We invited about 200 guests. They do have a deck and a gazebo that some of the guests can stand on but that won't be enough for all of the guests. Is it worth paying $2.00 or more per chair to have the guests sit or should they just stand on the beach for the 30 minute ceremony? Please advise
