intermissionless

From intermission + -less.

intermissionless (not comparable)

1. (US) Without an intermission; without a pause between acts in the performance of a play or in a film on television

   For roughly the next hour of the play's intermissionless 100 minutes, this sense of song weaving awkwardly through the prosaic, repetitive business of a party that changes little from year to year is wonderfully sustained, and it is a compliment to say that you are rarely aware of the period scenery (David Jenkins), costumes (Jane Greenwood) or the subtly shifting lighting (Jennifer Tipton). - [1]
