Unlike most places, Disney will always quote room rate as per room.
When they are quoting a package rate, that is per person, but a package will include the room and tickets and usually meals.
To get the single rate for a package take the following steps:
1. Double the per-person rate.
2. Subtract out the room and tax amount.
3. Divide the result by two, this gives you the per-person charge for the tikets (and meals).
4. Add back the room and tax amount. Now you have the single person cost for a package.
