LOVE LOVE LOVE the Park Hyatt Toronto.
I had the opportunity to stay at the Park Hyatt twice and was REALLY pleased with the accommodations. Rooms were big, bed were incredibly comfy, excellent views, great work out room, amazing view at the roof top bar, superb service and professional staff. The events and sales team were well-organized and quick to respond to any needs. There is even a driver that will take you anywhere in the city (for freeee!).
Though the Park Hyatt is a bit of a trek from the Convention Center, it is still conveniently located to the subway station just half a block down. What's even better is that the hotel is also close to a ton of shopping and theatres. Great location to stay if you're visiting for the annual international film fest.
I also had the chance to experience the spa at the Park Hyatt. WOW. Sure, everything was a bit pricey, but it was definitely worth the buck. I was more than impressed with the facilities and services. Relaxation couldn't be any more than this! If you're looking to take advantage of the spa treatments, be sure to ask about couples treatments.
