There are some great reception venues in the Canadian Rockies, that are not attached to hotels. From Golf courses to ranches and theatres, they all exist and have varying facilities. It is recommended that you visit and view the facility and ask what they have included. Some have Food & Beverage on location, others get caterers, some have Audio Visual equipment others rent out .
Always a great alternative is to discuss smaller venues that may be a restaurant. View those right here. www.banffweddings.ca/restaurants/
