If one of the pods is in Vegas, I'll bet the host casino will erect a practice ice or two in their conference center. That, to me is the best way to keep the team bubbles intact. Driving everyone to Fiesta or LV Ice Center doesn't seem practical, especially given the quality of those facilities. City National is the only NHL-ready practice facility.
My guess is that CNA would be THE practice facility. Say group A (two teams) has the ice from 8-9. Group B 9:30-10:30. Group C 11-12. (Then it could be "open to the public" after that.) (Assuming Orleans arena has nothing happening, they might install ice there for practice too.)
Meanwhile.... Pregame skates 8-8:30, 8:45-9:15, 9:30-10, 10:15-10:45.
(First group has no morning skate) Warmup 11:30-11:45; puck drop 12 (estimated completion 2:30).
Warm up 3:15-3:30. Game start 3:45 (estimated completion 6:15).
Warm up 7; puck drop 7:30 (estimated completion 10pm). If you need to do a 4th game, you eliminate morning skates.
Or something.
