keys: it depends on how old your ship is. If its an older ship then the room key is separate from your sail and sign key.
safe: It unlocks with a magnetic card swipe. Do not use your sail and Sign card. Use something else with a magnetic strip.
Muster drill : both of my cruises had them prior to sailing.
sail away party: On the Lido deck at sailing.. Its not organized and nothing is free but there is music. Grab a Caper at the pursers desk when you board and there should be one in your cabin when you can get into it.
Life is too short to let the ship of your dreams sail without you.
