I called the evening we checked out from my cell phone. (I used the number above.) Which was yesterday. I had no problem booking 2 rooms for next year. Since we had 2 adults in the room, I was allowed to book 2 rooms for next year.
They didn't even make us book in separate rooms. I told the operator we were coming back next year with my sister's family.
I was allowed to book my husband, daughter and myself in a room. And my sister's family in the other. I was expecting to book my husband and I in separate rooms. Made my life easier.
