Im scared to have a wedding because my hands sweat and I dont want to hold my fiance's hand while mines wet!!!?

so what should I do? Is there maybe a place where I could have the ceremony so that it could have a really cool temperature in the room? But how do I know it will keep cool enough with all the people in there? And can I even tell a building or church to change a thermostat's temp?! I need advice! I've always wanted a wedding but Im considering going to the courthouse just so I dont have to have the embarrasment of holding my fiance's hand while mine is sweating when were up at the alter OR while were having our first dance!
