Wow, you have some great choices there. California Grill and Narcoosees are a toss up as our family's favorites - the sushi lovers in the family prefer CG, and the lobster lovers prefer Narcoosees.
Good thinking leaving a few opportunities to hit Beaches & Cream. We tried to get in there on both of our warm weather trips and ended up at ESPN Club instead because the waits were so long.
Liberty Tree for lunch is quite nice, a little heavy to be what I think of as "lunch food" but so good you keep eating long after you're full.
For a lunch in addition to Via Napoli, have you thought about Teppan Edo? We really enjoyed our meals there, though if you have a teppanyaki grill close to home it might not be as special for you. We so seldom get to enjoy that style of dining and the food is just so good! It is one of my 12yo's absolute must-dos.
Oh, and those "eating trips"? They get addictive... We're going to be on the deluxe plan for the 3rd time in March, and now we're tossing around the idea of the platinum plan for DH & I (only - no kids!) for our anniversary trip in 2012. Eventually I'm going to try every TS restaurant at WDW, if all of our favorites don't keep getting in the way!
