Health chiefs are likely to be confronted by a noisy reception in Huddersfield on Monday evening.
The public meeting planned for the John Smith’s Stadium to outline why hospital changes are needed is the last chance for people to have their say.
Other remaining meetings in the consultation period are to give out information rather than see any debate.
All 520 tickets for the meeting, which starts at 6.30pm, have been allocated despite a few logistical problems.
But campaigners fighting to keep an A & E unit at Huddersfield Royal Infirmary are also planning to mount a noisy but peaceful lobby outside the Stadium, to let the health bosses know the strength of feeling.
The first public meeting at the Stadium saw many hundreds locked out and they kept up a constant chant which could be heard in the meeting inside.
A stirring video about the fight to keep the A & E unit and full services at the Infirmary has been made by Steve Mathan and posted on the Huddersfield A & E Facebook page.
It is shot with a drone flying above and around Castle Hill and features emotive comments about the fight to keep hospital services in “our town”.
