need dates!!

So tonight the husband and I have been burning up the websites for planning, i did find out from a friend that the school calendar should come out in January..which means we can have a set date and BOOK! We did price flights and are leaning that way, but we will see. I priced the vacation again and it went up over $600, same dates, same resort, same dining plan, park hopper SAME! So i hope we can get a date so when the next sale starts we can book! We are also talking about not waiting for fall break, but i really dont think its a good idea to pull a (then 7th grader) out for a week. We are getting ready to ask the kids about how they feel about flying but not saying anything about where, kinda round about way..lol
