A word of caution here-there are NO guarantees that your DCP will be able to get a discounted room-they come and go based on availability and not every resort is available for a discount (so if you are thinking guaranteed 50% of Grand Floridian-nope). Also the DCP will have to stay with you to get the higher discount and that will put 3 adults in a room-meaning the extra charge for adult that comes with it often negating the extra discount, plus those that sleep 5 are limited to mostly deluxe resorts which are more expensive anyway. What is most available is 30-40% off at places like Caribbean beach& Coronado Springs, Pop century. I am not saying that great discounts can't be had at premier resorts but they come and go very quickly. That said-Dd got a great rate for us at AKL studio (DVC) this past August! Probably the only time I'll be able to afford to stay there
Congrats to your daughter! Mine is applying for her 3rd program summer 2019! I used "disney math" to go quite often (got an AP, cheap flights, and when she could snag a good discount on room)
