A resort under renovation almost never closes. Work proceeds in sections, and the sequencing is driven by the need to keep selling rooms while a construction site operates on the property.
Rooms out of service are the real cost
A room being renovated earns nothing, so the calculation is between the length of the closure and the revenue lost while it lasts.
Taking a whole property down at once concentrates that loss and also idles staff who cannot be laid off and rehired without losing them.
Phasing spreads the loss across seasons and lets the operation keep running, which is why the work takes years rather than months.
Noise and dust define the buffer
Demolition and drilling carry through structure far beyond the room being worked on, so the units adjacent to a work zone are effectively unsellable too.
Properties respond by taking a whole building or wing offline rather than scattered rooms, since the buffer is cheaper as a block than as a ring.
Work hours are typically restricted to the middle of the day, which lengthens the schedule but keeps mornings and evenings usable.
Access has to avoid guest routes
Materials, skips and crews need a route to the site that does not cross pools, restaurants or the arrival hall.
That usually means using service roads and staging in a back-of-house area, and it constrains which buildings can be worked on at a given time.
A building with no independent access sometimes has to wait for a neighboring phase to finish before it can be started at all.
Sequence follows the season and the systems
Work is scheduled into the low season wherever the property has one, since that is when the rooms being closed would have earned least.
Shared systems set another part of the order. Replacing a riser, an electrical feed or a roof affects everything connected to it, so those rooms move together.
This is why refurbishment often follows vertical stacks or whole wings rather than the rooms that look worst.
What a guest can find out beforehand
Properties mid-renovation usually disclose it, but the useful detail is which building is closed and how far it is from the one being sold.
Asking for a unit on the far side, or on the side facing away from the staging area, is a specific request a reservations team can act on.
The other consequence worth expecting is uneven quality across the property, since renovated and original rooms sell side by side for much of the project.
