My husband and I got married in Vegas as a spur of the moment decision. (13 years ago) I had been married before and had a somewhat large wedding and yes- it was very stressful.
The Vegas wedding was so wonderful. We picked Treasure Island, but since the inception of the Internet, you could probably look at all the places offered within a short time frame with no phone calls. All we did was show up at the appointed time. They did everything- the flowers, the video, the music and the photographs. My only stress with that ordeal was finding suitable clothing.
We have recommended that type of wedding to anyone and everyone that will listen. If you can afford it, I say stick with your original plan and go to Vegas.
