My school uses WTW and Daily 5. I will say that different grade levels vary how they incorporate the two. I'm most familiar with what our first grade teachers do, so that's what I'll mention.
WTW time is a separate bit of time from Daily 5 for the lessons in small groups, especially when introducing new sorts. The lessons are short, following the guidelines the Sisters and brain research tell us about. The first couple of days are spent really looking at the sort and making generalizations (or discovering patterns), sorting and resorting the words. After that, the kiddos write the words (as best they can) in their WW journals, read to a friend and practice "old" sorts. Our teachers have the kids keep the words from each of their old sorts in separate snack-sized baggies in large brown envelopes so they always have those available.
This last piece, the revisiting of "old sorts", is easily transferred to Daily 5 WW time. Since the kiddos are familiar with the words in these, they can use WW manipulatives to practice during those rounds to cement the learning.
We also use a program for K-2 called "Phonics Dance" (not really a dance, but chants) to support both WTW concepts and Accuracy strategies. We feel that combination really is supportive of the CAFE strategies, and we see kids making great connections!
