Easy process. Very quick. The woman who did our paperwork loved her job--she was personable and genuinely happy for us. It's a quick 5 minute walk from the Fremont Street Experience parking garage. The only annoying thing to watch out for is that outside the building are solicitors--asking you about where your ceremony is, who is your officiant, yada-yada. I would just advise you to walk quick...without saying anything.
