It isn't perfect (especially for those of us who are used to it being warmer) and it has been a very cold winter for Florida. This week we probably won't reach 70 any day in Tampa. If you live here year around, I assure you 70 feels cold.
And, as someone who lives here, I hope we don't have shorts weather (by our definition) in April because if it is that warm that early in the season, we we will probably be melting by June.
They do close waterparks due to cold, but the OP was asking about rides. The rides are usually open unless they are down for refurb or closed briefly for storms.
