We are planning on going to Disneyland May 30th to June 3rd, 2017. Summer is already pretty crowded, but they just announced that all the Rivers of America Attractions and Railroad will be reopening on May 26th. Any guesses on how much of a crowd surge is to be expected immediately following this reopening? Part of me thinks it won't be an issue, as many of these attraction hold lots of people at any given time, and actually help to alleviate crowds in other areas of the park, but I was curious to see others' thoughts.
My guess would be that a lot of locals will show up for the first few showings of Fantasmic, but it won't have a huge impact during the day.
