Hey... A good ole Eagle here!
Respectful of time, family, economics, etc., week-long WB is THE only way to go. Echoing the comments from these helpful posts, nothing better cements a patrol, and the WB experience, but living and working together for a week.
When I took WB in 1976, weekend courses were just beginning. But I think they are great for reaching out to those with impediments in reserving so much personal time. I believe a good schedule of week and week-end courses should always remain in the program to balance alternatives to those dedicated folks who want to have a choice.
