We got married in Las Vegas also. Our wedding was at the top of the Stratosphere tower at night. In the chapel you could see the lights of the city.
For us it was worth it because of family drama. I hate family drama.
i have yet to tell my family or hers that we are considering this.. i figure we're gonna see if its something we 100% want to do before we tell them because we kinda already know their reaction.. right now we're like 70% towards a vegas gig
