Here is the final entry in this series, showing the full park at build-out. Thanks to everyone who commented & suggested paths for the adventure to take. A true Choose Your Own Adventure would have me do plans for some of the alternate choices. This ended up being an IP-free castle park, which is a pretty unique thing to consider.
-The final land is a village & estate based around a Haunted Manor E-ticket (not necessarily THE Haunted Mansion – maybe an original attraction).
-From both the DragonDale and Hub approaches, the Manor makes a formidable sight, looming upon its haunted hill, opposite a family cemetery that features in the land’s interactive mystery game (akin to MK’s Treasures of the Seven Seas).
-The ride showbuilding is hidden by a steep, forested berm with some roofline rockwork, if necessary.
-The second, family ride begins in the Stables (converted to a garage) as the loading station for an autopia style outdoor car ride (old hearses) through a haunted environment (graveyard).
-From the western Steam City approach, one passes through a Gothic townscape, home to dining and retail options and additional features for the interactive game.
UPDATE: Chapter VI:
-The added land is DragonDale, an original, mythical world of wizards, dragons, knights, ogres, etc..
-The park’s major atmospheric ride (an equivalent of PotC) needed a very large showbuilding; but one inside the berm. Like TDS’ Indy showbuilding, this one is completely adorned to become a themed architectural backdrop to the land: in this case an abandoned Dwarvish fortress-city in ruins.
-In the center of the land, behind and below the mage’s tower clifftop overlook, is a Coliseum that hosts live gladiatorial battles between various fantasy characters and monsters.
-The western side of the land is home to the fantasy townscape, while the eastern side is more rural/wild.
-The final land will be home to the park’s proxy of the haunted house-style environment/attraction.
UPDATE: Chapter V:
-Steam City is the retro-future, neo-Victorian land; a natural offshoot of 1899 Paris.
-I imagine it in a refined, art nouveau, but industrial (lots of smokestacks) style: iron, glass, brick buildings of unusual shape.
-The 8-turbine Hover-yacht docked near the Hub entry bridge would have polished brass and wooden trim.
-Everything is analog: working via gears, cogs, steam-power, Tesla coils, magnets, etc.
-The glass-roofed Les Halles arcade of Paris forms an indoor approach to this land’s center plaza, where an Orbitron-like spinner looms overhead.
-Steam Mountain is the landmark E-ticket with a test-track style ride system that sends vehicles careening on a banked, elevated track throughout the land.
-At least one darkride (based on an Automaton factory) and a Pandora’s Box simulator would round out the bigger attractions in this area.
-The Pulp Adventure area is really three distinct sub-lands preceded by a plane wreckage on a jungle island.
-Each land has an anchoring E-ticket ride (African flume safari(AA animals)/Amazonian jungle coaster around the Great Temple of El Dorado/Ice Age caverns EMV), as well as several lower-ticket attractions, dining and retail venues.
-The circumnavigating train passes through next-gen dioramas (e.g. AAs/musion effects) particular to that sub-land (Serengeti, Syberia).
-The most exciting feature might be the very large, “natural” Russian steppe inhabited by real, resurrected Woolly Mammoths. According to National Geographic, we apparently have the technology & knowledge to do this now(taking DNA from frozen mammoth carcasses, using elephants as surrogates): a real-life Jurassic Park. You will note the viewing paths over this plain.
