Going to be in Barcelona with my beautiful wife from June 15th-20th. Aside from the tourist/culture sites we plan on doing from 730am-2pm daily, we are leaving the kids at home and are looking for favorite venues that have a strong drinks/sexual energy, good people watching, etc.

We aren't looking for a swinger club environment. But perhaps there is a nightime beach full moon party where she can dance in their bikini all night.

Are there any specific beach or chiringuitos you recommend for a social fun atmosphere with flirty tones?

What about boat parties? It seems like there's only one company that dominates that market in Barcelona and the ads look like it caters to young college kids more.
