Hi, I can't really imagine walking from DI all the way over to
Crocs Bits n Bites in the DL Hotel for lunch. It's like WWS but not as nice; cafeteria style. WWS might be nice just because it's quiet and pretty, closer, and you can explore the gorgeous GCH lobby while you're there. Or, I'd go someplace in DTD for fun, like ESPN zone, RFC, or Ralph Brennans.
That's a lot of PS's. Do you want to do sit-down table service meals two or three times a day? Keep the PS's if you make them, but you can cancel or just not show if you want. You might want to consider getting groceries for your hotel room and having simple meals there during your midday break. Doesn't DI have a continental breakfast? Or is that the one I've heard is pretty lame, like stale pastries?
Also-- you're going to be there by lunchtime on a Thursday, and not go into the parks?? That's a whole other opportunity to explore, see shows and fireworks that first day. Check the cost of adding one day to your parkhoppers-- it's like $10 per person or so? Very very worth it for another half day in the parks. If I weren't getting there till 6 or 7 p.m. I could see not going, (although I would anyway

) but not when you're there by noon.
Just a couple thoughts I had, reading your plans-- good luck!
