I have a feeling the same will be true for us
we have already almost doubled our stay from last year to this.
The one thing that might stop us, is that we are doing Sunday morning to Friday night (13 days total) In order to stay any longer we would have to pay the premium cost of Friday/Saturday nights. at which point, we might as well stay the rest of the week too

hahaha so it seems like its 13 days, or 20
