Visited with Tilly Lodging field notes
Comfort Inn & Suites Thousand Islands Harbour District
A practical Gananoque hotel with a ground-floor sliding-door room and a small pet goody bag for Tilly.

The short version
Comfort Inn & Suites Thousand Islands Harbour District was our first overnight on the 2025 Eastern Canada trip.
There was a $25 per night pet charge during our stay. We were given a ground-floor room with a sliding door, which was excellent for getting Tilly in and out without working through hallways every time.
The hotel also provided a small goody bag with a couple of treats and some poop bags. The location made it easy to walk around Gananoque for a few hours before settling in.
There was a $25 per night pet charge during our stay, and the hotel provided treats and poop bags. Confirm current fees, room types and pet restrictions before booking.
