Did you consider doing 2 separate reservations? Not sure how long you are staying, but if you're doing a MYW pkg anyway, why not consider that so you'll get free dine for last days?

You can do room only (aaa? ) discount first 2 nights then FREE dine??? Just a thought.

We did something like that last year to get in on free dine TWICE! One was a bounceback and then public code released, we did a check out and then a check in and it was pretty much easy breezy.
This year we got in on bounceback so we booked for Free dine with that, then I got a PIN for free dine (first EVER!) so I was able to give it to my extended family for additional rooms (allowed to book up to 3 rooms, I re-booked under that code) WOW, they are thrilled, now it is public free dine during SAME period and some other family members have also jumped in.....I am PSYCHED, we're doing 11 days 10 nights and I can NOT wait....
