Get the Elvis package. If you are gonna get married in Vegas, then you should go all out Vegas style and get married with Elvis. It was done just right with some seriousness during the vows and a touch of fun with Elvis. Everyone had a good time.
My parents had such a good time they decided to do their anniversary here. The only con is that you cannot take photos inside the chapel, which was disappointing because I had a few people with great photography skills and great cameras.
