This is a very fun nightmare in space-Butlins! Some great stuff, I've put my constructive criticism below!
+ Great idea, really grisly and fun!
+ Short, snappy and concise, but full of flavour.
- The standard font is a little tricky to read/low-contrast on the turquoise backgrounds. It is okay on bolded text, but maybe a weightier font or a darker text colour like that used for the logos and tagline would be kinder on the eyes.
- Some areas are shown on the map (mezzanine and the lifts) but don't have discrete entries, this makes a little confusing to parse, not a major thing but it did stick out to me.
- The font for the headers works great for the title, but for the room headings it is a little harder to read.
