Wonderful
I've been in other Holiday Inn Expresses before, some kind of iffy, but this one was exceptionally good. Clean rooms and dining area. Nice pool (though kind of small, but it IS indoors, so...), and wonderfully accommodating staff. Though there was a long line for check-in, as all of us showed up at once, they were friendly, polite, and very helpful, even though we asked a million questions. VERY conveniently located, wow - literally a two minute walk to Lucas Oil Stadium gates. 
Will definitely stay there again if ever in Indianapolis again
