A Book for the Hotel

3Y1M:
 
A few days ago, I overheard my parents talk about going to PD again.  Excitedly, I asked them if we were going that very night or the next day.  Mommy simply said that Daddy must BOOK a room at a hotel first.  So I quickly ran off and came back with a BOOK.  Showing her the BOOK, I said, "I have a BOOK for the hotel... Can we go now?"  Obviously, I didn't understand what BOOK she meant.  Hahaha...
