I'm not just saying this because I'm a Europa fanboy, but what the toilets most lack is music
! It'd be so cheap and easy to put in, but would get rid of the way your suddenly yanked out of the escapism whenever you go to the toilet at Towers. They could use ITHOTMK, ride area music or even better, a custom composition like Lingering Moments at EP. Something really pretty and light-orchestral.
OK I'm going to be explicit, because this is a toilet thread anyway. If eating, don't read on. But the main reason public toilets need music is because of err... to disguise certain noises from other visitors who err, aren't feeling well! There, I just said it, what everyone's thinking. Don't blame me, I didn't start this thread, but that's why all theme park toilets should have music.
Apart from that the toilets at Towers are so outdated. Especially that horrible strip lighting. They're often not that clean either, the floors are usually quite wet. There should also be toilets at the Air end of Forbidden Valley, the Th13teen end of Dark Forest and most importantly, Katanga Canyon. Themed toilets please (the toilets at EP are absolutely sumptuous) or at least state-of-the-art toilets. Even Maccy D's toilets are better than Towers! Sort it out Alton! Especially the music, ASAP.
