CR CL is superior to AKL CL! The AKL CL is in a small attic like area overlooking the AKL lobby and has no view at all! It is small and we often could not get a table or even a seat. The food is fine, but the food in all the CL lounges is OK at best, IMO. Basically you get a continental breakfast, some snacks in the afternoon and a few appetizers or desserts in the evening (IF you happen to be around at the appropriate times). The food isn't worth the time to go all the way back to the resort and lose time in the parks, IMO, so breakfast is the only real benefit most days. In fact, the CL experience is more about the relaxation in the lounge area for us and that just wasn't even possible much of the time. It was just too crowded.
CR rooms are huge and comfortable on the 12th or 14th floor, with wonderful views of either Bay Lake or the entire MK area. The CR CL lounge has a spectacular view of the MK area with a large balcony that you can go out on to watch Wishes ( nice if you have the Bay lake view from your room). The CL lounge never closes at the CR (although food offerings are only out at certain times). It is nice to always have the lounge seating area available to sit and relax in. though. The CR lounge is larger and we never had any difficulty getting a place to sit here. Also, the CM's at the CR were friendlier than those at the AKL. CR CL CM's went above and beyond for us, even offering to bring a case of bottled water to our room for us so that we wouldn't have to be fetching it from the lounge all the time. These days, it is difficult to even get a bottle of water in many CL lounges, so an offer to bring a case to your room is rare.
Of course, the AKL is a lovely resort and we truly enjoyed our stays there. However, the MK resorts are all better located, have larger rooms and nicer CL experiences, IMO.
