There are several available accommodation options for the conference at varying price points. Here are a couple of the options:
1) There are affordable accommodation options on campus (traditional dorm and suite-style rooms) where the conference is being held. Prices are approximately $50 per night, per bed.

2) We have reserved a limited block of rooms at The Alt hotel in downtown Ottawa for $185 Canadian per night for a single-bed room. It is a 15-minute drive to campus from the hotel (and there is a direct bus route to campus just steps outside the front door).
