Hi Ce, welcome to the forum. Finding a wedding chapel in Vegas isn't hard, they're all over. Most are near the north end of the Strip and many of the hotels have chapels too.
My question would be what kind of wedding do you want, traditional, a theme wedding ( you can dress in medieval costumes at the Excalibur) or maybe you want an Elvis impersonator to officiate while you sit in a pink Cadillac, Vegas has it all. I will say the chapels in the hotels are much nicer, as some of the Strip chapels can be rather tacky, and I'm talking plastic flowers, battery-powered candles tacky.

I'm familiar with the Candlelight chapel near the Riviera Hotel on the Strip, it's nice however I encourage you to narrow your choices down and then go and look at a few chapels before your wedding, one of the pros of getting married in Vegas is short notice; trust me you do not want to choose a Vegas wedding chapel solely from a photo on the internet. Congratulations!

Keep'em flying
