I think it would be if you could manage to keep warm. I've always wanted to visit the Hôtel de Glace in Quebec City, too. I've been there in the summer and really liked Quebec City. Would love to visit again when the ice hotel is there.
Oooh, maybe that should be one of our trips. I ADORE Quebec City. As for the ice fishing, you build a bonfire on the lake, wear warm clothes, drink hot toddies and fish, it's good. Very good. :-)
Yes on the trip! :) I'd try ice fishing at least once. Fishing is kind of boring to me (short attention span and all), but the hot toddies sound good, especially shared with engaging company. :)
