Getting Nervous

so i found out the alot of my FH friends who are single and who we invited with a guest are bringing dates! but they are just bringing other guy friends who were not invited to the wedding!
basically so they can take advantage of the open bar/party! im sorry i dont wanna sound crazy because im all for parties and drinking! but umm its a wedding! about two people who love each other celebrating with their families and friends!!
and i mean, for the most part if you werent invited, you werent invited for a reason!

now im just nervous that my wedding is turning into a keg party!
