C1's lounge network is still small - only five locations with only one more publicly announced in the pipeline. I love bringing my wife to their lounges as an AU, but realistically we're only 1) together at an airport with a C1 lounge with 2) enough time to use the lounge a couple times a year. If C1's network were as large as the Centurion Lounge network (15), it might be more justifiable, but as it is, I don't think so. If our home airport had one, it would be an different calculation.
