I want to have my wedding on july 4th
What makes you think that a holiday is the best decision?
I want to do something different.
Your guests may have other plans for that day because it is a major holiday. Scheduling your wedding that day robs them of the opportunity to celebrate a holiday with their family, making them really inconvenienced with your wedding. Try to consider that and reschedule your wedding.
Is that is all you have to say?
Yes, I think that you might be upset with the turnout if you decide to have your wedding that day. That is the big reason I am suggesting that you reconsider the day.
