I actually fly with quite a few commuters that bid the CDOs because they are technically, commutable. The first day's show time isn't until 2000-2130 time frame and you are guaranteed to get done between 0600 - 0800 on your last day. You just have to find something to do with yourself during the daytime between the trips. After you use the 4 commuter hotels, maybe a drop or two or a transition legality, you have 4 days to worry about the whole month.

While I'm sure that 12 hour days in the crew room or crashpad isn't fun, they seem to feel its worth the ultra commutability on both ends.
