“Work‑from‑hotel” / day‑use and short corporate‑stay packages

• Several hotels run WFH or day‑use packages aimed at professionals (examples documented include lyf Funan, InterContinental, Marriott Tang Plaza and other hotels offering “work from hotel” packages with daytime room use, lunches, Wi‑Fi and meeting‑room add‑ons). These are useful for short business days or one‑day offsite work. (silverkris.singaporeair.com)

How companies typically set up corporate / negotiated hotel rates (practical steps)

1. Decide expected annual volume (nights or room blocks) and target properties/locations. Many brands require a minimum (or run tiered discounts at higher volumes). Example: Frasers asks for an estimated minimum room‑night volume when applying for their Business Travel Programme. (frasershospitality.com)
2. Contact Hotel Sales / Corporate Accounts or use the brand’s Business Travel / MICE online form to request a Corporate Rate Agreement / RFP (include travel policy items: rate caps, breakfast, Wi‑Fi, flexible cancellations, invoicing). Use the hotel’s meetings/events or corporate page for details. (shangri-la.com)
3. Negotiate commercial benefits to request: breakfast or F&B credits, complimentary room upgrades, access to meeting rooms, late check‑out / flexible check‑in, laundry credits, shuttle service, central invoicing and monthly billing. TMCs/OBTs (e.g., Egencia/Amex GBT) can help aggregate volume and negotiate better rates. (egencia.com.sg)
4. Get the corporate code and booking instructions in writing; ensure associates book through the correct channel (brand site / corporate portal / travel agency) so negotiated rates and loyalty earnings apply. Ascott and other serviced‑apartment brands require applying a corporate code at booking to receive corporate benefits. (ascottchina.com)

Other helpful resources in Singapore

• Serviced Apartments Association / consolidated RFP forms — useful when you want simultaneous quotes from multiple serviced‑apartment operators. (servicedapartments.org.sg)

If you need, I can (a) prepare a one‑page RFP template you can send to hotel sales teams; or (b) produce direct contact details / corporate sales email templates for the specific properties above.
