#2: Do you want to hop between parks?
Many people are not aware of the fact that there are actually two parks in Disneyland Resort. Both are well worth going to, so we highly recommend making time for both.
Additionally, these parks are within walking distance of one another, making it easy to walk back and forth. This fact means many people automatically choose the park-hopper tickets that allow them to visit both parks in one day. However, some people prefer to save a bit of money and stick with the single-park-per-day tickets.
