That is what I did. I booked the first 5 nights of our 7 night trip at POR with the gift card deal, with 5 days of the dining plan and 5 days of park tickets. I then booked 2 more nights with my 30% off pincode, and just paid the deposit. I can use the $500 giftcard to pay off the rest of the room, to upgrade our tickets to 7 day, and to pay for tips and oop meal costs. I worked on the numbers for most of the week. I was originally on the QSDP and had booked all 7 days with the pin. With the split-stay, I spend about $75 more, but get to eat at 5 TS restaurants. That seems like a better deal to me!
