Aria does not have any overnight accommodations to the best of my knowledge. And if you're coming from out of town I would avoid Waterbury as much as possible. I would look for an air bnb in Prospect, CT. If you must have a Hotel I would look to the Southington Comfort Inn. It's about the same travel time as the Waterbury hotel but you will be much safer. Also there are many restaurants and shops in Southington, CT (Chip's is a must try for breakfast).
Courtyard Marriott, Waterbury, Ct
There are limited rooms available there at Aria for guests for certain functions such as weddings to accommodate brides and grooms, etc. The Marriott Hotel is one that's nearby. You probably can google the rest.
Not much to choose from but there's a Courtyard by Marriott at 63 Grand street, Waterbury. There's the Quality Inn at 95 Scott road, Waterbury and then there's the Comfort Inn at 716 New Haven road. You can always find more, but these are most likely the closest.
