One person should check in at Pop to make sure everything gets activated; use the magic band to go into the room at least once and put a few things out to make it look like you're staying there.
So bring an extra toothbrush (like one you've got lying around to clean grout or something) and a few odds and ends. Maybe a duffel bag.
Everyone else should head to POFQ. The person who went to Pop to check in can then join the others at POFQ.
There was another post here where someone got a great suite off-site but wanted to keep their on-site reservation for the package, dining and tickets. Most people mentioned that their on-site reservation might get cancelled if it was obvious no one entered the room. So, you might want to have someone go to Pop every day to mess up the room, lol.
Just to warn you, it is not unheard of for Disney to cancel a reservation if they notice a guest has booked at 2 resorts for the same time period. It was a while ago, but one guest went to use dining plan credits, but found that room had been dubbed abandoned, and the package cancelled.
The other poster this week decided that they would use the package room for daily naps. You can not just have an empty, unused room. It will be cancelled, I believe.
The room is only 103 bucks with all those people on the reservation? Really! I want that. Hope you don't end up with a king size bed when you get to FQ.
