The marriage license office is in the Douglas County municipal building. It's open 9am to 9pm daily except 9am to 5pm on Sundays. Nevada marriage licenses are fully-recorded. The ministers, wedding chapels, and California notaries all issue state marriage licenses. On particularly busy Saturdays, the popular chapels will have a wedding every half hour from early morning until late at night.
Sunsets are the preferred time for weddings on the cruise boats.
Pricing is lower if you select a day-time ceremony. If Tahoe is your choice, you have picked one of the world's most spectacular settings for your wedding. There is no reason why you have to restrict yourself to a chapel for the ceremony. You can get married in your condo at Lake Village. Or at a waterfall.
