European clubs?

My husband and I are going on our honeymoon in a couple months and are going to hit Amsterdam, Paris, Nice, Monterosso, Florence, and Rome! What are some good edm clubs or rave scenes in those cities we can look out for? Also what should we expect to wear that’ll get us in the door? I’ve heard they’re much more selective but wasn’t sure how selective it could be. It’ll be our first time in Europe so I’ll take any tips or tricks you have! Thank you in advance!
