Ive stayed at WKL, WL and CBR, so I think I can lend some insite from my pov that may coinside with yours. WL is my favorite for sure. I really like the locale and taking the boat to MK, I prefer the boats to the monorail and when at monorail resorts still take the boat. The monorail always has and always will be a skytrain, which is our form of subway here, its in the air though, so its not exciting for me. The new DL monorails are actually built here by the same company, anyways....
CBR was good. We had dining while there too actually. I enjoyed the relaxed feel of the resort, we asked for jamaica and got it. Its about 5 minutes to the food court and main pool from there, and you walk over a little island with bridges to get there. The island is jammed with vegetation, a nice touch. The rooms are the same size there as AKL and WL actually, but they are mostly devoid of theming. Only mod with that size rooms btw. The nice thing about it is there are a lot more seats because its a mod at the food court. This doesnt really matter in off season and thats the only time we go but I could see the WL filling up at times. The pool was nice, the hot tub is always full, even in off season, its small and there is only one. I still like having it though and made use of it. The buses were good, its really quick to DHS, i mean 3 or 4 minutes by bus. Epcot was pretty close and its kind of central to AK and MK I think. I'd do this resort again all and all. No huge lines for buses like the values, far bigger rooms, and a nice theme for the place. Jamaican music everywhere, very cool. Not as immersive as the deluxes, particularly in the rooms, but nice.
AKL was amazing, the lobby is so stunning, just like WL's is. Its even more intricate I think, but it is darker because of how its lit with natural light at the back. Great though for sure. The animal view is so cool. We had standard and got upgraded, amazing luck. We had giraffes, zebras, ostriches, african cattle and various birds. All of them got very close quite often. They go off at night to sleep out of view it seems most of the time, but once a giraffe slept in front of our place. I found the food court to be better at AKL than WL, not just marginally either, lots of different type of stuff that was great, like the gyro type things, name eludes me.
Boma is probably one of the best if not best, restaurant at its price point. Do not let the fact its a "buffet" fool you, if you go there, make ressies for it. If you dont stay there its still worth it. Wow. Lots of books rave about it, and I agree fulheartedly. Buses, AKl is a bit out of the way, this doesn't bother me, some it may. Its probalby a 15 minute bus ride to MK, 10 to epcot and DHS, minutes to AK. Pop is about the same to MK though, so im not sure that really matters. Ive heard some peolple say things like its 30 minutes to MK, and thats just nonsense. It isnt possible to take 30 minutes to get from AKL to MK, WDW simply isnt ALL THAT BIG.
So thats my quasi reviews. Comparison? I wouldnt do Pop for that savings, some people swear by it, its not my thing, it could be if it was cheap enough, but its usually not vs a mod in off season. CBR v AKL for you. Thats a lot of money for 5 nights to upgrade. 1200. Hmmm. I think for us it was only about 450 to upgrade for 9 nights, exact same situation in May. There may have been a discount or something, and it was a no brainer. For that amount of time, I would not spend the 1200, not because its not a beautiful resort, simply because of my fiscal situation. Im not sure what yours is. To me, AKL is a steal because of the price compared to other Deluxes, I like it a lot more than other deluxes. I just think because Ive been to CBR and also like it, though not as much, I could be happy there and keep the 1200. I also really like PoFQ, different feel though completely. Thats my 2 cents, but it would totally change if I was able to make that upgrade and not be pressed financially, I'd do it. Also, there is every chance there may be a code for that time that comes out later if its not smack dab spring break time, which it may be. Hopefully my wishy washy opinion is of some help.
