We've given Iceland three tries and will not return. It's filthy and poorly maintained; short-staffed by rude employees; the rental skates are literally falling apart, with blades so dull that they won't grip the ice at all; ice condition is unusable, due to dripping ceilings that leave bumps all over the ice and infrequent use of the resurfacing machine (which is gasoline-powered, so there is exhaust in the arena). Miserable experience. Alpine arena is also old and rather run down, but it's much better than Iceland.
