Beer and wine or soju bar??

So we're getting married at a vineyard, and they do not have a full hard liquor license-- beer and wine only. BUT, they do have an option for a soju bar. Soju, the only way I had previously experienced it, is like a Korean version of vodka, but watered down. The venue explained it to me similarly, that basically it's vodka with half of the alcohol content removed so that it falls under the beer and wine license limits. The venue has not only vodka 'flavor' but all the other basics like rum, whiskey, and tequila. This option is only $5 more per person. Personally I feel like that's a weird thing to have to explain to guests when they ask what whiskey soju is, and my guests may be put off by it or feel like we're being cheap or something. Basically my question here is would you be put off by that at a wedding? Or would you just be thankful to not be limited to beer and wine only? (I should note my FILs are Russian Armenian and live on vodka). Thanks for the long read guys!!
