Too big a night in Puerto Iguazú

This evening at the Hostel Inn, I stuffed myself silly on the delicious all-you-can-eat BBQ dinner, I slurped away on the giant bucket of serve-yourself capirinha (after all, this is almost Brazil here), plus I enjoyed the great Tango show that they put on after the meal. Since I booked a tour to the falls for 9am tomorrow, that should have been all I did for the night. But I was silly enough to convince myself that I was being told the truth, when an Irish guy suggested that we go into town for "a few quick drinks". Hah: Irish — drinks — "a few" — "quick" — who was I kidding?! Anyway, I can't say it wasn't fun, staying out at the pubs of Puerto Iguazú until 4am; but as for tomorrow morning — that was Not Very Fun At All™.
