We'll be at Epcot on Sept. 10 (me, DH, DS 13, DS 10, DD 3). Currently have ADRs at Rose and Crown for 7:15pm, figured it would be good to rest & eat and have guaranteed good spot to view Illuminations at 9pm (we've never seen it before!) But now rethinking . . . 
Is it really necessary to use a TS to secure good viewing during off-season? We're on the free DP, & I could use those TS credits for, say, dinner with Cinderella at the Grand Floridian on another night. Epcot is said to have plenty of good CS options, so should we just grab a CS meal & wing it with viewing location, figuring the crowds won't be too much to battle? Any thoughts/experiences are appreciated!
