Lisa and I always try to go to the fort in October just for this and we always dress up. Lisa was a pirate and I was more of a train wreck last year but thats another story. Definatly dress up. I know our first year we were a little more reserved with our costumes,,,and then we saw how many people dressed up and decided to do more each year after. This of course works out for us because at home, we are the house people are either scared of or can't wait to see what we have done new. Before you say anything I am talking about on Halloween not the other days. We are just as normal as BDR when it comes,,,,,,wait a minute, bad example

. Anyway definatly dress up. Also, trying to pick the least crowded day is like trying to decide today what the weather will be like then but think about this. Orlando is still a major city ( at least to me it is ) and people there still like Disney or at least a good party. Weekends tend to fill up fast but midweek the crowd could be less( more of a chance that it won't sell out ).
