I got married in Vegas - a small chapel off the strip. I was on a budget and my fiance and I had family/friend all over the country. Since nearly everyone had to travel (and it's driving distance from where we live in SD), it was a cheap and convenient travel option.
Our wedding cost 3400.00 and included: chapel, minister, cake, flowers, photographer, video, transportation to and from the strip, champagne toast, DJ, open bar, chair ribbons, table decorations and surprisingly good food.
It was nice not to have to do a ton of planning, everything was handled perfectly by the venue.
Here is the place we used, it's not super pretty on the outside, but it was great.
