We've done the past 3 thanksgivings at WDW.
We seem to prefer a buffet.... let's the kids have other options (have one that doesn't do "thanksgiving food")... and well, being a buffet, we prefer that than a pre-plated meal on turkey day!
Did Chef Mickey's one year... was very good.
'10 did Crystal Palace - loved it!
'11 just did Cape May - really loved it - though, am a dark meat person and their dark meat was terrible (they had it sitting in a tray with water?)
Want to do Crystal Palace again - but they haven't been listed on the list of restaurants offering a TGiving meal. The year we went, they weren't either, but they definitely DID serve all the Tgiving fixings.
Going next Tgiving... and already trying to narrow down the choices.
Am thinking of Trails End... or Cape May again... or Crystal Palace if they offer it.
