Basically to estimate the package price for 7 nights for any hotel do this:
Take the rack rate for the hotel and multiply by 4, adding in sales tax at 12%. Rack rates can be found at

Remember the 3 extra nights are free.
Then add in $281 for each adult for the Ultimate Park Hopper Ticket (or $224 for each child). These are the prices for the 4 nights UPH passes, which then become 7 night UPH passes for free.
This is an approximation but SHOULD get you to within $30 of what they will quote you over the phone.
Sooooo....
For Contemporary:
Tower: $2062.8 for 2 adults or $2624.80 for 4 adults
Garden View Standard: $1632.72 for 2 adults or $2194.72 for 4
For poly:
Garden View: 1901.52 for 2 adults or 2463 for 4
Lagoon View: $2286.8 for 2 adults or $2848.8 for 4
Granted this is all approximate numbers but like I said before you should be in the ball park for estimating the package prices.
