My 2.5 y/o daughter is already chomping at the bit to get to WDW (it must be in her blood/genes). She has been to Disney on ice twice and Disney Live once, and knows that she can meet the Princesses and Mickey/Minnie at WDW. My wife and I have told her that we will take her when she is 3 years old. We are considering 2 options for the trip: (1) A November 2018 visit to WDW for 3 nights in which we would leave our current newborn son (who will be 12 months in November 2018) at home with my in-laws. (2) A February 2019 visit to WDW for 5 nights in which we would bring our then 15 month old son with us. If we decide to bring our son, we will wait until February so that he will be down to 1 nap and out of the bottle stage. Our plan either way is to stay at the Contemporary for the close proximity to MK. On one hand, I like the idea of the whole family being together. We will miss him very much if he is not with us. On the other hand, we will be able to get a lot more done without having the nap, early bedtime, and other schedule/logistical issues with a 15 month old. We will also be able to focus on our daughter who will love and get a lot out of this WDW visit (while our son at 15 months won't get anything except cute pictures out of the trip). I realize that there is no right or wrong answer to this question and ultimately, it is personal decision for each family, but I am curious to see how other families have handed this type of situation and if there are other factors that I haven't thought of yet. One more factor: After this visit, our family will be making annual trips to WDW so the question should be viewed in that context (as opposed to a situation where we would only be going once every few years or less often).
