Both have great qualities.
Both have car parks, a bar, resturant. The Radisson has a lovely terrace to sit out on on a nice day, and is in the centre of town.
Hudson Bay can be very hit and miss with the rooms that you get. If you are in the new part - perfect, you will be happy. If you get shoved into the old rooms, you will feel like you've been transported back into your Grannys era. Its very bad.
I would enquire if you could get a new room if booking there. Its gorgeous beside the lake, the Raddisson sits across from some houses and beside the river.
