I will always take standard view if I can get it, since it's such a large point savings. We aren't huge view people anyway. For our 2017 trip we got a pretty decent view - MK to the left and the lake to the right - and we enjoyed the fireworks. Of course, directly outside our room was some sort of industrial area, but it was below the balcony bar and hey - we were usually out there at night watching fireworks anyway.
When we end up with lake view (availability) I request one of the middle rooms, high floor, so at least we have that great straight on view of the lake. Which is nice and serene and lovely too.
There are definitely some crummy view BLT rooms though, so we've just been lucky so far not to get a really ugly one.
