I'm not an earplug person, and that's the last thing I would do on a vacation... <grin> But really, it wasn't a big deal for me to move.
In general, if groups of kids outside at 10PM would disrupt your sleeping, you could even just go around the corner of the building so you're not up against the courtyard. That way, you're not in direct earshot, but are still just as close to everything.
I'm not one to complain about kids just having a good time on their vacation.
