I am looking for advice on booking a 8 day stay in November 2019 or Spring 2020. We have a 40-50% CM discount so we are lucky to be able to go quite often but I like to make the most of the visit. Our previous visits were last week of October 2016 (right before Halloween) when my daughter was 25 months old (and 36" to ride Barnstormer!) and recently April 25th when my daughter was 3.5 years old and my newborn was 5 months old. For November 2019, my 1st daughter will be 5 years old and my youngest will be 2 years old. For Spring 2020 (assume another April visit), my daughters will be approximately. 5.5 and 2.5 years old. At that age, 5-6 months is huge so I am not sure where I am leaning. If I go in November, I can go again sooner...
I am fine with either date as the weather is LOW 80s and mild (for FL standards) too. There's a lot of dates being floated around for newer attractions so I am not sure what's been finalized yet.
Any advice is greatly appreciated.
