Here are a few:
*Have breakfast at Steakhouse 55. It's fabulous and a good bargain! My girls share food with us or eachother and they don't charge for sharing.
*Be sure to check out all of the memorabilia between the lobby and Goofy's/Steakhouse 55.
*Take advantage of the free coffee every morning in the lobby of each tower. They supply to-go cups and real cream.

Or, if you want one, request a coffee maker if there isn't one in your room. They often leave them out of the rooms but they have them if you want one; just ask.
*Don't miss the nice gift shop between the pool and the Wonder tower. Lots of glass, though, so caution is advised if you have small children with you.
*Be sure to check out the giant projected Tinkerbell in the pool at night!
*Watch for Goofy in the lobby.
*Compass Bookstore next door has some good options for quick eating on the way to the parks--Krispy Creme doughnuts, yogurt parfaits, fruit bowls, cereal, muffins, bagels, coffee drinks, etc.
*If you are unhappy with your room (for a reason other than you'd prefer something better but didn't book it), don't hesitate to say so at the desk. Don't touch anything in the room, just go back down and tell them it isn't acceptable for X reason. We booked a 2-queen room and were given a
tiny room that was only large enough for a double bed. I'm not kidding--it was postage-stamp size. We went back to say uh-uh (nicely) and were given a king suite overlooking DTD! Another time, our sink backed up in the middle of the night (we were in bed at the time and hadn't used it) and they moved us to a nicer room plus gave our family a free breakfast buffet at any of the character meal locations, plus unlimited fast passes! We are normally not complainers, but sometimes you have to, and in my experienc DLH has always made it more than worth any hassle we've encountered. We've stayed there many, many times with no problems, but the few times we've had something happen, they've been very good to us.
Enjoy your stay!! If I think of more, I'll post later.
Oh, noee01, I don't know what PDFs are (flotation devices?) and I don't know the answer to your question--sorry.
