Have stayed club level at AKL, WL and GF RPC. GF RPC has the nicest lounge, but AKL is a close second (at least when it used to overlook the lobby -- I'm not sure where it is now). Our GF RPC stay was very recent. Breakfast was good, snacks okay, desserts good, evening appetizers were quite unimpressive I thought, especially given the price. What was missing? Shrimp in the evening, berries in the a.m. to name but two little luxury items that ought to be served when one is paying $700 per night for a room. I suspect that making sugar loaf club level and insisting on serving exactly the same items at both places is responsible for the less than stellar food. I think the food is geared to what sugar loaf patrons are paying (rather than what RPC patrons are paying). The price differential apparently is attributable solely to the location. Too bad, actually.
We loved AKL club level -- but our stay was 5 years ago. At that time, there were delicious and luxury level appetizers each evening -- yummy shrimp, good (not green like at GF) beef on skewers, hot soups, etc. We loved it. Given the overall decline in dining quality at WDW, however, this may have declined as well. Let us know what you find.
Enjoy!
