I am planning a 5 night break in Toronto in early December with Mrs Airframe from the UK.

Have never been to the city before so am looking for hotel advice please.

Would like to be close to attractions in downtown area something around 4* standard preferably.

Will be taking day tour to Niagra falls / visiting CN tower / theatre and possibly the zoo. Aswell as shopping and general hanging out in the city.
Any other attractions/places not to miss out on ?

Thanks for advice.
