I live over in San Diego, and have watched their AHL team (Gulls) quite regularly. Tickets START at just over $30 (£25), but that gets you nosebleeds at the top of a 3 tier, 18,000 capacity arena.
Tickets closer to the ice with a similar view to Devils games will set you back far, far more.
Average attendance is approx 7000, so the reality is watching a lower-half team in a half-empty rink.
Despite current ‘woes’, I’d choose a night at the Devils every time!!! (and did over Christmas, watching them 5 times on my visit back to Wales!)
