Hi, Shawn!
According to the calendar on
Disneyland.com's website, it looks like the fireworks are only on Friday, Saturday, and Sunday nights throughout the month of May.
The last week of May, however, it looks like the fireworks will begin showing nightly, since the park is open until 10 PM.
Hope this works out for you!
We are doing the last 50th Anniversary Tour next Friday, since that is the only day that they offer the one with the fireworks seating, even though they are showing fireworks all week.
I thought that was strange, but I guess they don't have as much of a demand for the tour on weekdays?
Now I just have to hope for clear skies, as the 10 day forecast says there's a 60% chance of showers!
Best to call and find out, although you can't book until you're within 30 days.
Have fun!
Rose
