Rolling pin bakery tasting?

We are going with rolling pin for our cake since it comes with no charge from SLCC. Anybody here have a tasting with rolling pin? How does that work? You place an order for what you want to try and then you just go in, pick it up, and try it at home and then let them know what you want?
It's about an hour away from my house and seems like a waste of time.

Did you get the petite size to taste or the large split cake?

I was planning on ordering my samples next month (we have to go to that area anyway), but I am kind of curious as to what size I should get.

I just have to let my venue know what I want though, so I'm going directly to the bakery for samples but not dealing with them after that, only my venue.
