1. Take them for a ride. Transport your guests from the ceremony to the reception tourist-style. You can hire a local tour company to pick everybody up and give them a brief tour of the area as they head to the reception venue. Want to skip a formal tour? Give them a spontaneous one as you "joyride" between events. Look for a trolley or ferry that can hold all your guests, and treat them to a free ride.
2. DIY Photo Booth. Instead of doing a traditional photo booth, put a unique spin on it. Create your own backdrop, props or gag items to make a theme for the booth. It's simple, and the possibilities are endless.
3. Try wine-tasting stations. Instead of having a signature cocktail, host a beer or wine tasting. Present the top picks from the bride and groom to make it personal; and to add authenticity, bring in a sommelier to introduce the wine and explain to guests how to properly cleanse their palate. An added bonus: Give your guests monogrammed wine bottle holders as favors.
