Hi All, I'll soon be heading to Disneyland, I will be purchasing a 3 day park hopper. The trip is pretty spur the moment, and I already had a trip planed for later in the year, and possibly another. With all these trips planned, it will be cheaper if I just get an AP. If I so chose, how would I go about upgrading my park hopper to an Annual pass? Is that even an option? I've heard it mentioned before, but I'm not sure if you can actually do it. If so, does it need to be done before all three days have been used? If I chose not to use one of the three days, could that day be credited towards an AP? I rarely get to go to DL, so these things are foreign to me. Also, the park hopper was purchased at a discount through AAA, will I need to pay the difference? Any help would be appreciated!
