I just received the 3-9 stay, play & dine offer, too! Seems like a great deal for us with a 6 yo and 8 yo. We weren't planning a trip this year, but this may be too good to pass up (and I DO want to go back before we would have to purchase an adult ticket for the oldest).
However, I'm wondering about the fact that the packages always seem to include one fewer hotel night than park day. So that means that you go to the park on both of your travel days, right? So you are essentially losing part of the first and last park day, it seems to me. What does everyone here do with these types of packages? Do you purchase additional hotel nights, or just use the package as-is and go to the park on your first and last travel days?
