In an interview with the developers at Blue Tongue, they mentioned several buildings they wanted to include in this game, but had to drop due to design decisions or memory constraints on home consoles:

•Hotels, which would provide extra accommodation for guests.
•Dino-Vet Station, which would have been vital for keeping dinosaurs healthy.
•Hunting Platforms, which would let visitors hunt down carnivores in the park from afar.

The Dino-Vet Station can be found in earlier promotional material for Jurassic Park: Operation Genesis and also within its game files. Likewise with the Hunting Platform, which also still has Audio, Ini and even Rig Files within the game.
