Due to personal and religious reasons we are having a dry wedding. Our cocktail hour is re-named to social hour

we will be serving appetizers and have a photo booth so people don't get bored. But I'm worried people will get tired of water, coke and tea (hot, sweet, unsweet). Any drink suggestions we could add that will be fun for our guests? like a DIY flavored water station or something?
Re: Dry wedding
How do you plan to flavour the water? Could be good, but depending on how you plan to flavour it, your guests might not want it (fruit vs. a flavoured dye). Otherwise I think still and sparkling water alone are good.
Anything else you add is nice, but not necessary- juice and lemonade.
You could do a similar thing with lemonade - offer a regular lemonade and an infused version with blueberries or strawberries.
Otherwise, do you have any local sodas? For instance, we have a local soda company that bottles soda made with cane sugar that are pretty popular and come in cute glass bottles (I think they do strawberry, strawberry rhubarb, orange cream, cream soda, root beer, black cherry, and grape). It's sort of along lines of Jones Soda, which is also really popular. Depending on your budget, you can also have a DIY Italian Soda station or hire a bartender to make them (which might be easier and better all around). Buy a variety of syrups, have carbonated water/club soda, and cream available.
@sparklepants41, the mocktail idea is fantastic! Maybe a signature mocktail for each of you in addition to the other offerings?
"You want a coke?"
"Sure."
"Okay. What kind?"
"Dr. Pepper."
