I'm cruising on Liberty on May 9th. I was reading on the "Onboard Experience" that there are theme nights and/or parties on each ship. How do people dress up and participate if they don't know what these nights are specifically? How do they pack accordingly? I noticed that many of the themes are specific enough to where prior knowledge and packing would be necessary in order to REALLY participate. How does this work?
Thanks in advance for your help!!
