We're going to Disney this year! Hooray! We have 2 available weeks to choose from -- should we go Labor Day week (starting on Labor Day or the day after it) or the week of October 7? We know October might be a little cooler, but we have heard things about the lines starting to get longer in October and with 3 little kids minimizing lines is a priority. Is it true that lines are reliably shorter in September or not? Please advise!
