I believe I've read 10 or 10:30pm meet in the lobby. 11pm cruise. People seem to get back to the Sens around 3am-ish.
We met up for the cruise at 9:45 in the lobby. Buses leave around 10. You get back to the hotel around 3 AM. The pirate ship was probably the most fun event for us at Sens - felt very much like PatyO's (but on a pirate ship lol).
We brought up the pirate ship in our FB event yesterday and one of the girls had an outfit pic from Yandy posted and ordered within like 10 minutes. I ordered my wife 2 outfits today, one I pieced together that will be quite revealing, and a cheap fallback one if she doesn't think she can pull off the other. We should get good participation from the rest of the group too. I'll post up everyone's info in our event later tonight; thanks for all the info!
