Cosmiques refuge will be open if you're looking for a refuge, it's open much of the year unlike the Gouter refuge. There is also the 'abri simond' if you're just looking for a free roof over your head. It is technically forbidden to bivi at the cable car station but people do it. Abri Simond/Cosmiques refuge would be a better starting point for an ascent than the aiguille du midi station anyhow. To save on weight and bag space I'd just pay the money and stay in the refuge and get fed too.
Also, if you're planning on descending by the gouter be advised - expect a killer of a descent, having just climbed up to 4807, you'll then have to descend 3800 vertical metres on foot to get back! The TMB from Nid d'Aigle to Saint Gervais opens mid june and the cable cars in Les Houches later still. The only mechanical way down is to descend the way you climbed, back to Aiguille du Midi. There are other descent options such as the valee blanche and take the montenvers train or Mulets route and go to the mid station of DuMidi but they can provide big route finding problems and dangers at that time of year. Early June I'd go back the same way I got there.
