Did anyone sign up for package at Baby spa. Was it worth it? How long is the swimming for?

I bought an inflatable tub on Q10 and enjoyed baby spa in the comfort of own home.. however, agree with some parents that draining and filling water (have to add hot water too if not LO will get a cold) is tiring (we treat it as a form of exercise) Also discovered cheap plastic balls on Taobao so bought 200 balls at $7.. so the inflatable tub can dual use - swim and ball time
