Historically F! has ended it's nightly run early, but fireworks were presented nightly through Labor Day. There hasn't been a nighttime-specific parade in a while, so no one really knows what they'll do about that in the fall. With Labor Day being late this year (Sep 7), it's harder to say if they'll have the same schedule as last year (when Labor Day was September 1). I'd tentatively guess that they'll present fireworks and PtN nightly through Labor Day, but there is always the chance they'll end nightly presentations earlier. The operating schedule is generally posted about 45-days in advance, so information won't be known until late July.
