Wedding Cake Delivery

Alright, I might be going crazy, but I'm considering using a local bakery that doesn't offer delivery. Wedding cakes aren't really their specialty, but they do make them and it's a lot cheaper than anything else I've found (about $2.50 a slice!) I love this bakery and everything I've had from them has been delicious. They've totally open and encouraging of my crazy cake ideas.

The bakery is about a half hour/20 miles away from my venue and it's all pretty much straight highway. But, they don't deliver. My venue can't keep the cake overnight. I can probably have someone pick it up the night before, but I'm not sure where we can keep it. The only option I can think of is if someone gets an Airbnb we might be able to keep it in the fridge.

The other option would be having someone get it the day of the wedding. It's buttercream and my wedding is in October in Maine so I'm not worried about heat. I just don't know who would have time or if I'm creating an unnecessary complication.

Does anyone have any other ideas? Or should I give up on this?
