It's a totally different vacation staying multiple days, as opposed to "annual passholder daytrips" (I grew up in Anaheim, worked as a CM, and it wasn't until we moved 3 hours up the coast that I was able to enjoy DLR as a RESORT).
My advise, talk to people in line...talk to A LOT of people in line. People at DL always seem friendly and open to chat...especially if you have a lanyard with pins on it to chat about. Somewhere, in one of the lines, you may hook up with a group that is there "sans spouses", and you may be able to hang out with them for half a day.
Also, chat with the cast members, you can learn some amazing stuff from them.
