Golden ticket is a sort of a Pass that allows you to earn rewards on the upper side of the screen. It helps you receive extra rewards that are not available to players without the Golden Ticket.
For example: Rewards circled in red are available only if you buy Golden Ticket, otherwise as soon as you complete some tasks you'll be able to claim rewards on the lower side of the screen only.
You need to complete daily and main tasks and the boat will move in accordance with the points scored.

Daily and main tasks may be the following (as an example):
The Golden Ticket is valid only for one Travel Season. For the new Travel Season you need to purchase new Golden Ticket. You can see the duration of the Travel Season under the icon in the game. You can see the number of days until the end of the Travel Season also there.
As soon as the Travel Season is over the Golden Ticket expires and becomes unavailable, as well as the rewards. Please keep it in mind and count the time left if you decide to buy Golden Ticket by the end of the Season.
