I am attending a conference at the JW Marriott in Indianapolis and I see that the Fairfield Inn & Suites, Courtyard, and Springhill Suites are all in the same close vicinity. If I was to pick one of the latter three to stay at, which one would you recommend? Easy access to the JW is the most important factor for me, followed by comfort and amenities. I don't want to be wandering around in the dark to get back to my hotel room at night. The conference is being held in JW Conference space (i.e. not at the Convention Centre). Advice from locals (or those who know Indianapolis well) greatly appreciated!
