Rarely use it in Dance music myself, as dance music mixes tend to be very wet anyway.
I find with good application of compression, nice analog EQ (and of course, tape saturation) the mix saturates and blends nicely without having to add reverb as well.

I use master verb with rock music, particularly as I am never there to record source, so the instruments are rarely recorded and treated in a unifying way, so master verb helps to gel things together.
Most dance music is "made in in one go" and so the sound tends to be, mostly but not always, more tonally coherant.
