I think something as important as a muster drill should be monitored. I mean the ship shouldn't be able to leave without confirming (like sending in a report in a sense) that it has been accomplished already. The situation is just a mess. I believe even on shorter (not like as soon as you leave you arrive) cruises should be mandatory.
They just removed another piece of track from the truck. I'm not sure if they will get another piece up today but we should see another 2-3 pieces or more up tomorrow.
