I don't know where you got your Cabana Bay price from but for 2 adults from June 29th for four nights in a standard room, it comes out to $664.20. So, if you add in two Three Day Park to Park tickets, the cost is $1,061 after taxes.
Now this is where things get bad. The SAME dates and details but with the package, you are paying $1,164. So, if you book this "Special Package", you are really getting NO VALUE. In fact, you are paying $103 MORE if you book the package compared to booking the room and tickets separate. Hopefully both breakfast's are free or that "Special themed Welcome Parcel" has $100 bill in it.
