I'm actually not going till 2017, but will be doing January after the Disney Marathon and before the Martin Luther King Holiday -- mini trip four nights / three days. I was originally going to do March over my son who is in college's spring break, but I didn't like the crowds I saw for the afternoon at the Magic Kingdom after the Keys to the Kingdom tour, so am trying January instead when the crowds look manageable. This was based on ride time wait projections in touringplans.com. Sure I might be able to get a few fastpasses, but not for everything that would have long lines in March. DS doesn't start his spring semester until after the MLK holiday, meaning we can go at a non busy time even though we are tied to the school schedule.
Plan A -- This is if just DS and I go
Rent car
Stay at Disney Springs Holiday Inn four nights -- getting a double queen room with pool view and balcony
Day 1 -- SeaWorld
Day 2 -- Magic Kingdom (Keys to the Kingdom tour, followed by doing our favorite MK attractions)
Day 3 -- Disney Hollywood Studios
Plan B -- This is if DS, DH, and I go. DH doesn't care for Orlando, but DS thinks he should come down to see the Harry Potter stuff at Universal since he's such a big Harry Potter fan. DS would like to show DH this.
Stay at Cabana Bay at Universal for four nights -- just so we can get early entry to the Universal Parks and we'd stay there the whole time, just so we don't have to move.
Rent Car
Day 1 -- SeaWorld
Day 2 -- Magic Kingdom (Keys to the Kingdom tour, followed by doing our favorite MK attractions)
Day 3 -- Park Hopper at Universal
