When we send invitations for the wedding in May we will send one to each person over the age of 18(plus date). Right now I'm in the process of DIY-ing STDs. Is it Ok to send STD's to "The Simpson Family" instead of 1 to parents, and 1 to each adult child at the house? This would save a lot of money.The back of the STD has information about the hotel we've blocked rooms at. Would it be helpful for them to know that each family member can bring a date for the purposes of booking hotel rooms? Cliff's notes: do STD's need to be sent/addressed the same way invites will be. Or does "Simpson Family" suffice?
