Hi,I was wondering if I have 7 day park hopper plus tickets for Disney World,and I upgrade them to 10 non expirational days,would I be able to use the remainder of the days I dont use at Disney Land? My family is taking a trip to Disney World in January and then me and my daughter will be going out to California for a family function in May,and I was wondering if I could add on the extra days and the non expiration to our passes and maybe while we are out there,we could visit Disney Land. If I could do it this way,it would only cost me less then 150.00 for those extra days for an extra trip. I am hoping! So does anyone know if you can use Disney World tickets at Disney Land? Thanks ahead of time for your help!
