The full span of the first reservation, unfortunately it is only 2 days long.
We are 2 days at poly, then 5 at old key west, then 5 at beach club. Tomorrow I think I will be able to use the old key west reservation to book a few more ADRs.
You should be able to book 180+ 10 on the phone for a split stay. If the Cast Member isn't aware of that, call back.
