Are reply cards needed?

So we are only having about 30 people at the wedding in San Diego and money is pretty tight since we are trying to pay for as much as possible on our own (including the AHR). Is it really all that necessary to send reply cards out to those people who we already KNOW are coming (flights and hotels booked)? I am thinking of just including reply cards to those who I am unsure of...but is this poor ettiquite? At this point, we are willing to do just about anything to save some bucks

Just have everyone email or phone in responses - saves WAY more money.

I would just have them RSVP by another means such as phone, email or your website. Save the money... especially w/ all the brides on here who have sent RSVP stuff and then say a lot of people don't bother returning them. I asked for a preliminary RSVP and I kept getting comments of "I don't really need to do it do I... you know I'm coming."

Yeah I was going to suggest the website response. I know at least on the Knot the website is free and your guests can RSVP there too!

theweddingchannel.com and brides.com also both have free websites that you can setup and people can rsvp on. I'm not bothering with rsvp cards especially after hearing so many other brides stressing about no one sending them back. that would just piss me off if i spent all the money for them and no one replied.

We bought a one year subscription to the weddingwindow.com for $80 and they have an online RSVP option built into our wedding website.

I'm not sending reply cards either...but our wedding website has an RSVP function and most guests have been using that. If you dont want to bother with a website, you can just include your email when you send your invites and ask guests to RSVP that way/

Not at all... I have a DW specialist that organize the people that book. I also got online RSVP emails back from my website but when people started to inquire - they all changed their minds because the trip was too expensive for them.

Thanks for all the suggestions girls! I think I'll go with the website, since I can do it for free on my knot page...thanks!
