I live nearby Warsaw and want to go to these two places next Wednesday or Thursday.

I saw online that the admission is free on Thursdays but does somebody know how crowded it usually is in that case?

I don't want to spend money on buses to later find out that access is restricted because it's overcrowded, in that case I just prefer to go on Wednesday and pay the tickets (reduced fee so not that expensive).
