Vacilando comes from the verb vacilar, which has several meanings depending on the context. While it can mean to hesitate or waver, in the context of this song and Caribbean Spanish slang, it means to party, have a good time, or chill out.

"Vacaciones" opens the morning after a blackout night: "Me desperté, en la sala de una casa ajena" (I woke up in the living room of a stranger's house), boots and empty bottles scattered around him. Instead of regret, Wisin turns the wreckage into a punchline and a philosophy — he never needs a real vacation, because he treats every night like one.
That's the hook: "Yo no necesito vacaciones, ni dolores de cabeza / Solo me basta mis amigos y un traguito de cerveza" (I don't need a vacation, or headaches / My friends and a sip of beer are all I need). The rest of the song is a running list of what actually fills that space — a pool party, a nonstop "rumba," dancing until his feet swell — proof that for Wisin, the good life was never about the destination, just who's around him and how loud the music is.
