Where to Stay, What to Do

Explore Carmel


Just a 30-minute drive from Indianapolis International Airport, the Carmel office is a handful of miles away from old town Carmel’s Arts and Design District, the Clay Terrace outdoor lifestyle center and The Fashion Mall at Keystone. 

Find indoor and outdoor shopping centers, casual to fine dining and varied entertainment nearby. Indianapolis, nicknamed Circle City, is home to the NFL Colts, NBA Pacers and Old National Center. See the monument downtown, bike the scenic Monon Trail or stay in Carmel for music at the acoustically perfect Palladium. 

Several hotels in the area qualify for a MISO corporate discount. Below are three. You must call in order to get the discount: 

Explore Eagan


MISO’s Eagan office sits in the Boulder Lakes Business Park Complex, just five miles north of downtown Eagan. For easy access to rail transport and the Mall of America, plan to stay near the airport. Families love Eagan – home of the “Heavyweight Champion of Cool” – for its Hennepin Theater District and Cascade Bay Waterpark. 

Explore museums like the Walker Art Center and get tickets for sporting events like hockey, baseball or NFL games. Eagan is fit for a short business trip, a weekend family getaway or both at once. 

Explore Little Rock


The “lifeblood of Little Rock’s downtown scene” is the River Market District, home to an array of food vendors and live entertainment. See Arkansas’ minor league baseball team, the Arkansas Travelers, at Dickey-Stephens Park after browsing the Clinton Library. Get a taste of The Natural State’s history, culture and BBQ at local museums and restaurants like Doe’s Eat Place. 

Ask for the MISO corporate discount at any of the following hotels:
