I'm pretty sure it's 10 days online and at 6:00am at the resorts. I always do advance check-in (since we can) and it makes check-in a LOT quicker and faster.
Thanks for the "reminder". I'm 8 days out and just did mine for the 21st.
!0 days before your arrival date.
We had a split stay in DEC and did on-line check-in both halves.
Loved it as we left BWV after bell services took our bags and caught a DTD bus. Transfered to OKW and got our packet as soon as we arrived.
