Jell-o shot travel

Hello! Extremely dumb question here! I will be traveling rather far to visit some family and there will be a party tonight. I have some leftover Jell-O shots from a party a few nights ago and I was thinking to bring it so they don’t just go to waste. problem is I will be driving three hours to get to my location. I was wondering if I put them in an ice cooler if they would last and if not, would they be able to reset in the fridge once I get to my location? I know you can reheat and reset Jell-O but I don’t want to reheat it now that it has the liquor in it. Is there anyway I can get these safely to the party or is it a lost cause and I should just throw them away and make more when I get there? Thank you greatly for any help. Cheers!
