There are definite differences from an agronomy standpoint (more humid climates in states east of here better support year round bermuda, even if it goes dormant).
Also, many Arizona courses all but require carts, either because of mountainous or real estate design factors (usually the latter) and you really can’t have carts out on dormant bermuda all winter. That’s why many places like the Sandhills have been able to go dormant, the courses allow it, because they are walker friendly. Furthermore, as much as they are a tourist destination, they aren’t a winter tourist destination first and foremost. They do fine with a lot of their winter play coming from locals and the locals are just fine playing on dormant (often painted) turf.
None of that is true here. Most courses in Arizona make the majority of their budget from Dec-April and the tourists coming during those months expect the green lush conditions. Eagle Canyon can’t charge guys from Chicago $200/round in January if the course is brown (or only painted green), but if they aren’t getting $200/round in peak season they aren’t going to survive long.
And, even beyond the cartball thing, desert designs don’t do well dormant. Apart from Apache Stronghold, the only other course I can recall trying to go dormant was Vistal (which closed years ago). It was a decent track, desert style, kinda on the side of South Mountain. But a desert course playing dormant and thus, season goes on, very fast/firm, gets kinda out of hand. In my experience, the ball just wouldn’t stop until it found a bunker or some desert. Not every course would be this way, but an awful lot of courses out here are built in hilly areas.
With all that said, I have always though munis should go dormant. While they might be getting some tourist rounds, they are still ultimately community courses and never moreso than in the winter when everything else is so insanely expensive. Encanto, GCU, Kenny Mac, and many other munis would play great dormant, they’d be open two more weeks in the fall, and you’d save a ton on water, fertilizer, and seed. The cart thing would be a concern. I don’t now how much cart traffic dormant bermuda can truly take, but these courses already let carts out in the dormant bermuda rough (granted this is maybe a reason they have a very hard time with transition every spring).
