As head chaperone of our WDW Senior Class Trip, we always go the third week in March....because for the past ten years I have been planning the trip, both Water Parks have been open, and the water parks are always a highlight for the kids and chaperones alike. Plus it is a good time to go without missing standardized testing, drama productions, and athletic competitions.
This year we have a trip size of 162. Many kids were upset to learn that Typhoon would be closed. I was disappointed that although hours were posted about 6 months in advance, it was decided 27 days prior to close not only an attraction or two, but an entire Park.
In the days where you are to book FP rides 60 days in advance, and therefore create schedules around those rides, it would be cool if Disney were more firm on nailing down refurbishments of entire Parks. We are disappointed, but will still have a nice time on the trip. And I fully believe this is a cost cutting measure-refurb is not extended for work, but rather to just save operational costs for another week of very low water park attendance.
