I'm assuming that there will be coordinated meet and greets for all of the DIS boarders on the cruise? I know our group is so large that this will be difficult to coordinate.
Not activities, but things I've been thinking about...
It would be great if DU sent (or distributed) all of us some sort of tag/lanyard designation that we could wear throughout the cruise to identify ourselves to our fellow podcast cruisers. I saw it mentioned somewhere else - but I had totally thought of it too - it would be really cool to have magnet signs or something to put on our stateroom doors (if we wanted to of course) to designate ourselves as podcast cruisers.
An activity idea would be an informal schedule of suggested group activities, i.e., XXX night in XXX bar at XXX p.m., adult cruisers should plan to meet up with other podcast cruisers. There could be one of these per day. They wouldn't require any hosting or coordinating, just a distribution of the proposed schedule so we could all connect if we wanted to.
Personally, I'd love a tour of that suite - but that seems a little pushy and invasive.
