(This review is purely based on my experience with the conference centre.)
I visited the Novotel a couple weeks back to attend the 2017 Mississauga Sports Summit and was very impressed with the overall quality of the experience.
I'm a bit surprised by the bad reviews on this place. It had been several years since I'd last visited the Novotel (came here for a gala nearly a decade ago), but I seemed to recall that the place was still very classy and modern, and I was glad to be proven right.
They certainly run a tight ship over there. Lots of modern amenities like wi-fi, buffet-style breakfast down in the mezzanine for the conference and very clean rooms for the discussion panels. I'm unsure what others were expecting from this place, but I found it to be a very nice experience and a welcome change from the norm. The conference ran like clockwork, and all the facilities I saw were clean and well-maintained.
It's a hotel that I'll likely be back to in the future.
