we are planning a September 2017 trip and we are planning to attend the MNSSHP the first night we get there. ( if dates hold true from last year). The plan is the catch an early flight, 5:30 am, get to the hotel, then go to Disney springs for the morning and lunch. Then hit the party at 4:00. What are the chances that we can get an appointment for my two daughters at the boutique at Disney springs before we go to the party?
