The Grand Tour

The Grand Tour is a main quest and achievement/trophy in the Fallout 4 add-on Nuka-World.

Detailed walkthrough
You've met the bosses of the gangs. Now it's time to begin the conquest of Nuka-World. For every park overtaken, hand it over to a preferred gang, or a despised gang. Get the gangs beside you, or at your throat.

To complete this quest and achievement, the following quests must be completed:
 * A Magical Kingdom
 * A World of Refreshment
 * High Noon at the Gulch
 * Safari Adventure
 * Star Control

 * At the end of the quest, talking to Gage does not allow you to continue the quest.
 * This should be fixed with version 1.7.19, but some reports don't confirm that.
 * After finishing speaking with Gage at the end of the quest the game has an error.
 * When you complete A Magical Kingdom and clear all the other parks before starting this quest, the quest log will keep telling you the locations are not secure and not show that Kiddie Kingdom can be given to a gang.
 * The only way that seems to fix this is to deselect the quest in the Pip-Boy log, save, quit, then reload. The quest will update and tell you that you can now assign Kiddie Kingdom to a gang, but still tell you that the other parks are unsecured. Clicking on the flag at the parks will still let you assign the locations and the quest will move on to talking to Gage.
