Great location for Indy meeting
I attended a convention at the JW Marriott and was impressed not only by the physical plant (to be expected) but especially by the friendly, outgoing staff. Marriott staffers were abundant in the lobby, and they knew how to engage their guests.
The bonus is how well located this hotel is. It's a pretty walk to the zoo, and wonderful museums are literally across the street. If you really want to explore, ask for directions to the bicycle hub that partners with the YMCA. Good bikes at nice rates.
The conventions meals were quite good, and the breakfasts were are attractively presented as any I've ever seen.
