This will be your biggest project!

I work in hospitility (OTA) everyone is scared of this transperency existing. All the sort order is rigged by margin vs. conversion optimization algos. Every long term hotel collegue only stays at new hotels but they are so hard to find. There are public companies that are build on hospitality intelligence and they suck. You can easily monetize this with 15-20 cent per click, even if you only use one of the big providers (insanse!).
