Mykonos in June

My husband and I are planning a trip to Mykonos + Santorini June 12- 21st. Our budget is pretty flexible and we are looking to have a good time at beach clubs, night clubs, etc. is the crowd and vibe still going to be fun? I heard that July and August are much better. We don’t care for large large crowds we just want to have a good time and still get the full experience.

Also feel free to give us any recs as it’s a very last minute trip! We were originally going to go to Mallorca/Ibiza but the partying in Ibiza felt very college spring break vibe and we def like more lux and mallorca feels like a good place to bring our kids with us vs Mykonos feels like a good couples trip.
