You can, but you might not want to. Our experience in a 2BR at VWL was that the four of us were perfectly comfortable. It seemed that six might be tight. Eight would be hard to imagine. The common area space is quite small---one couch, one easy chair, two bar stools, and two kitchen chairs.
I'd recommend a resort with larger common areas for a party that large. For example, at OKW we thought six would be perfectly comfortable, and eight would be tight but doable. AKV-Kidani might be a good choice too---I think those rooms might be a decent size, and the third bath might come in handy.
