stupid question about Actors' Fund performances

I know these are stupid questions, but since I've never been to one of the extra performances on behalf of the Actors' Fund, I thought I'd ask. Would one expect that these performances are different than other performances (curtain speeches, more celebs in the audience, etc)? Are these performances discounted by the usual mechanisms (broadwaybox-type discounts, TKTS, etc)? (If not, I would imagine that some of these performances are somewhat sparsely attended.)

Actor's Fund performances are the best to go to! Every time i've gone, I've seen tons of celebs and had funny curtain call speeches. The most memorable one involved a conversation with the cast from Gypsy after its actor's fund performance!

seems to be that the actors funds benefits are perfect times for other actors in other shows to see shows they wouldn't be able to see otherwise because of same performance schedule.

or is that just a duh thing, and i was the dumb one who actually took time to write it out? lol... it's late, i'm rambling. :)
