Just an idea. For seven of you wanting three rooms, it might be better and much much cheaper to rent a large house. With the cost of a 5-bedroom, being about one value room, you'd have money for a rental SUV, Uber fares for when one vehicle wasn't enough, G+ and IA$$$ for everyone for every park day, some nice meals and still have money left over.
One thought, with the only real remaining on-site perk being the half-hour early entry, it now easy to put a price on the on-site perks. People should be able to do one IA$$$ for free with standby during early entry. So, the value is whatever the IA$$$ price is multiplied by the number of people that can make it to the ride. If they do a Running Of The Bulls during early entry, some people won't get any benefit. If they do a controlled CM walk, then everyone that can wake up early should.
