I also would like to stay with 24 hour. In another game we went to longer periods and I found it hard to stay interested (and remember what was going on). Short attention span I guess.

Exceptions can be made for anticipated problems. In addition to waiting as we did Last week-end, players can get someone else to play their turn. Or if you choose the 'AI do nothing' setting and fill your queues, you can let the AI play one turn without too many dire consequences.
