While I understand some things do run out, you can, by and large, arrive at any restaurant at closing time and still receive the full menu. I agree it doesn't make sense to waste for the sense of waste (i.e. for an empty room) but if someone walks in within the service window THEY PAID FOR they shouldn't find only crumbs of food and no beverage options, as people here have described. At the very least, the person on duty should ASK them what they'd like.
If you got any other buffet, which you paid for, 30 minutes before closing and they have no food do you say "that's life"? I seriously doubt it and this is no different. If they want to shorten service times, OK, but the times they list are the times and food should be available throughout. Period. ... And I say all this having stayed at various club level resorts and (happily) partaking of almost nothing but toast and diet Coke.
As for why someone who has not yet been to Disney club level would dare comment, as another poster asked (with eye-rolling emoticon) ... Why does it matter? Because, as a paying customer (and Disney definitely wants my extra $$$ for club) I'm reading this thread and not only seriously reconsidering my club-level stay, but staying on site at Disney at all.
I can stay at the Ritz Carlton in Orlando, which I know from experience has outstanding club-level service and vastly superior restaurant options, for LESS than what I would pay to stay at the Polynesian. For my husband it's not even a question. He wants to switch. Period.
I don't need someone to email me back and forth about restaurant reservations when I go do them myself online in half the time. (Or email back and forth, as I already have, only to be TOLD to do it myself online. Great "service" there.) And, other than the lounge, I don't see any other perks I would actually use, other than, perhaps, in-room souvenir shop delivery, a negligible benefit at best.
