It would have to depend on the difference, and if YOU want to stay at a moderate, or if you're happy with ASMo. We stayed at CBR on our last trip and we loved it. We chose ASMo this time because our budget is fairly strict this time, and we can stay longer there than we could at CBR, by one night.
I have considered upgrading our stay to CBR IF a good enough discount code comes out, but we might just stick with Movies.
If it's worth it to you, and you have the extra, go for it! If you are happy with ASMo, use the extra $$ for a character meal, or something the kids want to do.
Good luck!
