Contrary to what one might have heard there is no off day or season in Orlando when touring the attractions. With the rare exception of an attraction closing due to to inclement weather - for example, a hurricane warning - the attractions are extremely busy every day of the year. This translates into long wait times for all rides - sometimes in excess of 1 hour.
Tickets are expensive; obviously one wants to get on more than 4 or 5 rides. Use these tips to tour Universal Orlando Resort like a Florida native and there is no reason why any family shouldn't be able to get on each ride during a one day visit.
Now, go out and have fun on each and every ride! For more information regarding current prices and hours of operation visit Universal Orlando Resort's official website.
