Boat party is a must do, ive done many, quiet pricey except the ones with package, with a club u are willing to go ,that night eg Paradise, Carl cox Revolution
i will pay attention to choose my boat parties now , but for a first time u should go for it & upon ur taste of music pick the boat party that may fit ur tastes.
for opening ive choosen a team Odyssey Events,that don't represent ibz boat parties on the whole but price is fair & good quality music as in 80% they play EDM & its not my kind even some may like it...
for the non commercial boat parties i will say Lost in Ibiza, float the boat avre hardly recommanded
Pukka boat boat is quiet fine, a mix of commercial & kickinh House Tech house
Ocean beat party,beautiful people , cirque de la nuit too pricey, for a first time i guess ucan afford it..
best boat parties are private ones i na yatch(never succeed to get in) or workers ones (i did some)
