Weddingbee boards

I am using ewedding.com.  I am not computer saavy, and found their options easy to use.

i was originally looking for a free website as well (and i even made a couple) but they were such a hassle and really not what i was looking for, so in the end i paid for one with weddingwindow.com and i am soooo glad i did.  so far our guests have seemed super impressed with it and it was pretty easy to create (a bit time consuming, but not at all difficult).  so its not free, but i would check it out.

We are using weddingwindow. It's not free but it's really super nice and easy to use.

YES! mywedding.com does all of the above and it is free and super easy (much more user-friendly than the Knot IMO).
Here is what you wanted and how mywedding.com does it:

RSVP - It has an RSVP page you can activate which allows you to also keep track of meal choices if you want. You can export your RSVP list to an Excel sheet with one click.

Maps - your guest can look at and print out maps - all you need to do is make a custom page using their template and enter the Googlemap URL.

Registries - it has a registry page template. Enter in as many stores as you like.

Allow guests to learn about you: Create the "Our Story" page using the template. And you can also add photos to the "phot Gallery" page and activate the Blog page if you wish.

Guest to enter which hotel or other info - Create a "contacts" page using the template for this. The contact page will allow guests to directly contact you with questions or comments. You may view and reply to these contacts from this page. You can also activate the Guestbook and have guests put in their hotel info when they sign in, but I think the contact page might work better for your purpose.

I feel like a commercial for mywedding.com but I LOVE IT. Their tech support is super helpful if you get bogged down at any point in the process.
