How much is cocoon in August?

i've spent 65 for the closing buying the ticket stright after DC10 (unformal closing party) and entering the cocoon party by 2 o'clock :)
so generally the openings and closings are much expensive than regular parties? even if it's high season?

June/July is usually 40 - 45 Euro, August is always 50 as its high season / the busiest month, September is around the 45 mark and the closing party up to 80 Euros.
