A reset is not half a clean
The instinct is to divide the existing service into two shorter visits. That produces two inadequate attendances rather than one good one. A reset has a different purpose: it returns a space to a usable state between two groups, which means furniture returned to layout, surfaces cleared and wiped, waste removed, consumables restocked and the floor spot-treated. It does not need the detail work that belongs overnight.
Write the two as separate task lists in the scope. The overnight service carries the substantive cleaning: floors, detail, glass, amenities in full, and the rotating periodic items. The reset carries a short defined turnaround. Keeping them apart makes each one checkable and prevents a contractor under time pressure from performing two partial services and calling it a full schedule. It also gives the contractor a defensible position when a short window prevents part of the reset.
