Danbury has come along way since it burned by the British in 1777. See it here:

On a more serious note,
All the hotels are going to be pretty safe. The Courtyard is brand new but open long enough to get the bugs out. Not a particularly attractive property.
All the hotels have easy access to 84.
I forgot about the Springhill Suites I'll have to check that out. That was a new building.
