Do people really think it's ok to just show up to your wedding with out telling you?
Sorry, but I must agree with all the ladies. It does sound a bit rude, or a bit pushy. We all know how you feel as most of us went or are going through it. We have set up a website on which I have provided all details and then once a week a do an update. If there are particular people I want to come, I've already talked to them; they know all the details. You can't really make people rsvp, especially for a DW. This is the harsh part of DW. Keep in mind that a lot of people will wait till last minute to book hoping they'll get a 'last minute' sell out. Some of my invited guests have told me they might 'surprise' us and just show up. I've included a note about element of surprise for a wedding on my website. Politely saying that I have to notify the resort's WC about number of people for my wedding etc etc. (I'm not a fan of surprises for something I'm putting a lot of effort planning).
Don't stress over the RSVP. When people are ready to book they will. Some people will not even tell you they are not coming. My wedding is in Sept. I sent out the invites in January. I didn't even bother with RSVP cards (I thought it was a huge waste of money and stamps). Since I did passport invites, I dedicated a whole page to Reservations and RSVP. Asked to be notified by phone, email, via website or in person by July 1st if they are coming. Gave my self 2 months to order more favours etc.
