I'm thinking about booking a 5 night cruise out of LA on Bliss that departs on October 31. I figure there will be people decorating their doors (not my thing) and people dressing up.    What has your experience been  like when taking  a cruise over Halloween on NCL? Any fun activities that NCL normally wouldn't do but do because of Halloween?    For people who dress up, did you dress up just at night or do it the full day?
