I love CSR -- we were there in July with DS 12 and DD 10 and we all loved everything about it, including the pool, and will go back there. However, when my kids were the age yours are, we stayed at POFQ and I really suggest you look at that. The POFQ pool is just made for little kids -- it has the cutest water slide that is a magic dragon's tongue. It sounds weird but is adorable, and is great for the little kids. Find some pictures of it, sorry I am incompetent linking pictures. Parents can ride the POFQ slide with their kids, which you can't do at CSR. My kids now think the POFQ pool is too "babyish" for them but they still love it because of how much fun they had there when they were "little." Plus POFQ is a much smaller, less spread out resort and will be lots easier with little ones. You will be happy at either resort!
