I think the article nails a lot of the big points and is certainly helpful for the thrifty bride. In my opinion you really only need a few things to make your wedding reception great: 1) Alcohol 2) Great Music - pretty simple list, but really that's ALL it comes down to! With a strong honorable mention to a Candy Bar - ha ha ha! Sure you can spend a bunch on the coolest chair covers and bling bling centre pieces, but really it comes down to you and what kind of party you're trying to throw. If you're looking for fun - great music, beer, and good friends will do the trick!
