You might want to use one of the available codes for a "room only". I think WL Courtyard discounted rate for that period is $149.00 (not incl. tax of 11%).
Then you could try one of the discounted ticket outlets, i.e.
www.ticketmania.com and order Park Hopper or Park Hopper Plus tickets. Of course you don't get all of the features of the Ultimate Park Hopper and the pins, but I guess you'd have to decide whether the cost is worth the difference.
Based on my quick calculation of $149 + 11% = $165.39. At 6 nights, that's $992.34. With 5 Day Hopper Plus tickets, that I believe are including 4 options (not 2), at $251.00, or $1004.00, your total is $1996.34.
I think the UPH ticket includes Disney Quest, but you can get a discount on ticketmania on that as well ($23 adult, $19 kids, I think). So now add that $84 and your at $2080.34. About $100.00 difference so far. IMHO, I think you're getting a pretty good package price.
You'll have to decide whether you're paying for some things you might not use with the UPH ticket, but you do have the pins as well.
That's my 2 cents worth, and regardless of which way you go, I'm sure it'll be fun.
