Just wanted to let you know, and I'm not sure it'll work for you, but I called about our November trip today. I had to wait list some days, which equals split stay for us.

Anyways, our ADRs open soon so I asked about having to add ADRs based on check in. The CM on the phone told me to call the morning my first reservation opens up and they can override the system and add the rest of the reservations manually for me. Just thought I'd pass that along, he also said there's a possibility the computer would just let me book the entire stay. I'm not sure it'll work for you, but it's worth a try.
