ski dubai

The child bride (she's only 67) and I just got back from three safaris in Zimbabwe and Botswana. On the way back to Vermont, we spent three days in Dubai where we got to experience Ski Dubai. It was fun but the novelty wears off after two hours. Nonetheless I'm glad we did it.

Are indoor ski resorts possibly viable? How much size, vertical drop, and slope pitch might a resort need to be minimally interesting enough to draw customers? And have some of them occasionally return? Do such resorts need to be near large urban areas in order to have a ready customer base...
