Context-aware flow in the booking engine
From the package page → package preselected in the booking module, going directly to room selection. In this flow, the package comes before choosing a room type.
If someone selects a package with limited availability (such as the Easter package), it is important that this can be passed along so that a visitor can only select the valid dates for that package from the main domain.
From the room page → room preselected, with packages prominently displayed as optional add-ons (possibly in a separate step). At the moment, the packages are somewhat hidden.
The selected product should always remain visible throughout the flow (confirmation of choice), in every step.
