So I finally just set the last of my no-responses to "no" on my RSVP list. My RSVP date was June 27th and the RSVPs were supposed to be online, by phone call, text or email (basically however they wanted).
I realized that even with phone calls and emails, there is no point chasing down people at this point. People who haven't booked their tickets by now, aren't suddenly going to do so, especially when they realize that a $700+ plane ticket plus $200+ per night hotels aren't going to fit into their budgets.
I only have 2 more people who are probably "no" that are still on the guest list (why, I don't know, maybe they did buy tickets and didn't tell me). So I guess my decline rate will go from 74% to 76% any day now.
Why did I waste my time and money planning a wedding? I honestly don't know.
33 days until this is all over.
