Reply to mini portable speaker

I'm heading to a resort for a week with a load of other folks for a friends wedding. I'm bringing a controller (twitch) and my laptop in case there's a chance to plug in poolside or at a disco one evening , but was believeing it would probably be good to have something portable to bring for the late evening hotel room afterhours mayhem.

Doesn't have to get me kicked out...lol - any suggestions?

Cheers.
