Wedding insurance for our reception?

Ok here it goes. My wedding reception is going to be at a fishing club my uncle belongs to. For some reason we need insurance. My parents got a good price for my sister's wedding (a little over $400 for 1 million $ coverage), plus at her wedding she had a lot of friends that drank a lot but no one drove home druck and nothing happened. Well, my fiance's father thinks we should go with his insurance which is $1500 because he thinks we need it. We do not really have any hard partiers comings to the wedding and I think everyonje will respect us. By the way both of our parents are paying for half but my parents are giving us $6,000 toward the wedding. I would like to save some of that $ for our honeymoon and only spend $6,000 but if we go with his father's way of thinking we will not have much money left over and my fiance does not care. What should I do please help?

How much coverage for the $1500? I know that 1 million sounds like plenty of coverage, but if you have someone get into an accident that could be exhausted very quickly. Is his father friends with the agent that is quoting $1500? More info please.
