A.C.
I married my British husband in a Vegas wedding; our 4 year anniversary was a month ago! We have a 3 year old and an 8 week old, and life is awesome! But we're stronger and better as friends and a couple now than we were then.
My old roommate's parents were married in Vegas like 30 years ago and are also still together.
Personally, I think all the stress, bickering, lack of teamwork and joint input (the guy usually just does nothing and has no say in more traditional weddings), "this day is all about me" type mentality that goes with big weddings, plus beginning your new life together grossly in debt is not a great way to start a marriage! We opted for Vegas because there was a little something for everybody, and what we did was a reflection on BOTH of us, not just traditions that don't really relate to our everyday life. My husband could get excited about it as well, and from my experience, that made it different and special!
