We stayed at Star Ranch for a wedding in Dripping Springs and over New Years. It was great for a big group. We had 12 people, but we really could've fit 13 people in beds. There is a king in the master, a queen in one guest room, 5 single beds and a full-size bed in the bunk room, and a pull-out in the office. This doesn't include couches or places for blow-up mattresses either. The guest room and the bunk room have a Jack-and-Jill type bathroom. This is in addition to a half-bath, the master bath, and a giant full-length mirror in the entry way, which was perfect for all 8 girls to get ready.
The only reason I am giving 4 stars, instead of 5, is the fact that the fridge/freezer broke halfway through our visit. The property manager didn't see my message right away. When she did, she came right over to check it out though. Unfortunately with it being right around New Years, no repair man would come out. Thankfully, it was cold enough outside that we could keep the salvageable food out there in coolers. The property manager also offered to go get us a giant cooler and ice if we needed it.
Overall, I would definitely recommend this place!
