Hi Candy, I typically take a taxi/uber, the event is pretty much self contained at the hotel, it will just sit there.

There is also a shuttle service from the Avid Hotel to the Ingleside Hotel if you are staying at that hotel.
Unless you have several in your group arriving at the same time and are planning to sight see some after the conference... A rental car is not that economical... Like Frank said... it will most likely just sit there.

How much did the taxi/uber cost, do you recall? I am trying to outweigh the cost of using a transportation service versus just renting a car. My former boss and I generally drove up to Wisconsin, so flying in is new to me.

Candy,

My first time also, I am driving in from Chicago but was weighing Uber earlier.. it looks like less than 50$ for an Uber X from Mitchell to Hotel..

I pulled my Uber receipt from last year and it was $60.99 for the airport to Ingleside. That doesn't necessarily mean a whole lot because of flex pricing. And if its an early morning flight out be sure to schedule your Uber.
