If you're looking for a unique and beautiful wedding venue in the Dallas area, I strongly recommend the Museum of Nature and Science Planetarium. This is where we had our wedding, and it was absolutely perfect. The dome planetarium is great for weddings with under 200 guests, with comfortable seats and a beautiful back drop of the night sky. There's a nice wide aisle for the bride to walk down, a stage for the ceremony to be held, a great sound system, and an absolutely stellar light set up that can be adjusted as need be. The planetarium offers all the beauty of the night sky without the noise of passing cars, the cold wind, or the bugs. My husband is a huge astrophysics buff, so this was perfect for us. It's not a very common wedding venue, but you'll want to book early just in case. The museum was very helpful and allowed us to view the dome for free so that we could check it out. The wedding package includes a show of your choice, or for a little bit more, you can design your own- we went with a slide show. You can even have a laser light presentation if you want.
