Tricky question
Ibz town (Nightmare Parking issue ☝ u got only bars at harbor, Lio (for rich people, not a lot of people can afford 200€ diner with a show ), Destino by 8-10 miles (not on my minds even i ve already been there when there was no party just for some drinks and chillout music, quiet empty that day)
Pdb (bars in pdb strip from popular one eg Murphy's bar to fancy one eg Nassau +Bora bora beach/ el Patio beach club ); Sa trinxa Salinas beach (bar) not so far by 5-7 miles
San an West end (Itaca bar, Plastik Lineker san an bay ,o 'beach, Bambuku ibiza rocks, ibz rocks bar Kumharas San an bay (bar) savanah cafe, mambo cafe )
I will suggest San an but a car is more than recommanded this year (Exploration and bus is to avoid because of mass gathering and and as frequency is low we can expect delay to pick bus as if packed to satisfy social distancing, u may queue for next one)
Are bars in westend will be allowed at night? (looks like not) places such Hush ibz? (hanging in westend is not my thing but this year u can't be picky ?)
