As with any other tourist city, seasonality in Orlando is normal.
Each season can change your experience completely. Everything can change from one
season to another from pricing, waiting times, traffic to everything else.
Seasonality is not only reflected in wait times at the parks; like everything else
in lif prices are affected by supply and demand. During peak seasons you can pay
more than double for a hotel compared to a slow season as well as restaurants (in
case of Disney)
