I would suggest delaying your flight home and work on the premise that there is guaranteed to be a gathering at more than one dark sky site somewhere in the country on the new moon weekend.
Wait until the weather forecast is available and catch a flight to the best (clear option)
Flights in this country are generally speaking, not that expensive - like around a hundred Euro - and can be booked with short notice.

I am sure you will have no trouble finding someone happy to give you a lift if you keep in contact here on this forum.
Be aware that when you are browsing for flights online, that companies (like webjet) use cookies to track your browsing history. The price will be higher the second time you make an enquiry, and higher again on the third.... if you delete your cookies, the price will come back down. They do it to get you to panic buy.
The skies down here are spectacular and well worth the extra effort.
