Just be kool, smart and pay attention to the simple rules and all is fine. According to HAL you can bring wine, sparkling wine, soda and water on board for personal consumption for consumption in your stateroom . Just pack it well and bring it, it's ok and don't make a deal about it. I've never had a problem. As far as dress is concerned, i've been on many trips... no one really cares what you wear.. This cruise is a charter so HAL really isn't even involved,and 1200 lesbians are pretty flexible.
