Creating Packages (Per Person or Per Room?)

When you create packages for folks other than couples (say a girlfriend getaway or a mancation- hate that term, BTW) do you price it out as per person or per room?

I'm thinking of doing a pkg that I would price per person, double occ, rather than by room. Do you find this works, doesn't work, depends on the pkg being offered? I guess I look at it a few different ways: 1. the price looks lower per person; 2. it's easier for me to price it that way; 3. it's easier to keep track of '$99/person' rather than 'it depends on what room you choose' which involves multiple price points. (In the 'per person' scenario, someone might get a better deal than someone else, but I'm hoping to price it out fairly evenly. Or even add a simple 'upgrade fee' for certain rooms.)

If someone wants to cram 3 people in one room, it's still $99/person. If they only want 2, it's still $99/person. The only thing it wouldn't be valid for is one person in the room.
