Kingston isn’t too far from Ottawa, but if you’d prefer to stay overnight on Saturday, here are some accommodation options.
If you're from RMC, this should be a problem;)

Hampton Inn by Hilton Kingston
125 Innovation Drive, Kingston, ON K7K 0H4, Canada
Option for a hotel if needed - Has been tested
Hotel
Holiday Inn Kingston Waterfront by IHG
