Good point, WDWmo, this is about visiting Quebec City, one of my favourite places to visit. And when in Quebec City, you will be hosted by folks in the tourist trade who are friendly and welcoming to visitors in many languages.
(And ABSimillard is absolutely right! I learned Portuguese from my Montréal neighbours, who manage to keep their language just fine, thank you, as are my Anglo-Quebecker friends. As for my Franco-Albertains and Franco-Manitobains friends, for example, keeping the language has been much more challenging.)
As for location, at the Château Frontenac you will be ideally located for enjoying the bounty Quebec City has to offer. Good restaurants, lots of real history you can see and touch, great music and cultural offerings galore, especially around St Jean Baptiste; you've gotta love it! Enjoy!
