This is a phenomenon that has never quite made sense to me. Here in the UK we have a lot of people who like to drink. We have lots of places that sell alcohol. We have even more places who sell alcohol for insanely cheap prices. Yet, despite all of that, we still travel abroad in our thousands to get drunk in other places. Ibiza is one such place; but going there simply means you’re surrounded by other Brits.
It makes no sense to me at all.

You are paying an enormous amount of money for flights, then even more money for hotels and then even more money for alcohol and entry to clubs simply to be surrounded by Brits. Something that you can do for free at home. The only thing that you won’t get here, sometimes, is the weather you’ll get abroad. But who cares about that? Save yourself some money and some embarrassment.
