Short answer — in three places:

1. Major hotel chains’ corporate / meetings pages — many Colombo hotels publish business / corporate packages (meeting rooms, airport transfers, fast Wi‑Fi, business center rates). Check the corporate/meetings pages of hotels such as Cinnamon Hotels (Cinnamon Lakeside, Cinnamon Red, Cinnamon Grand), Shangri‑La / Galle Face, Taj Samudra, Berjaya Hotel Colombo, Marino/Marine Bay and other large Colombo properties and request their “corporate / business travel” or “meetings & events” packages directly. Berjaya’s meeting-packages page is an example. (berjayahotel.com)

2. Online travel/booking portals with “business” filters and package bundles — Expedia, Booking.com/Agoda, Trip.com and KAYAK let you search business‑friendly hotels or bundle flight+hotel packages and show business amenities (Wi‑Fi, meeting rooms, breakfast). Use their “business” or “business‑friendly” filters and the package/bundle search to compare rates. (Expedia.com)

3. Sri Lanka corporate travel / destination management companies and local travel agents — DMCs and corporate travel agents can negotiate group or recurring corporate packages with hotels (airport transfers, preferential rates, day offices). Examples include Walkers Tours / John Keells inbound services and other local travel operators who arrange corporate stays and meetings. Contact them for tailored business packages.

Quick steps to find and book:

• Decide must‑have amenities (meeting room, reliable high‑speed Wi‑Fi, airport transfer, daily breakfast, flexible cancellation).
• Search hotel websites’ “Meetings”, “Offers” or “Corporate” pages and email the hotels’ sales/reservations team for corporate rate cards. (Often better rates than OTA listings.) (berjayahotel.com)
• Use Expedia/Booking/Trip.com/KAYAK to compare business‑friendly hotel listings and package deals quickly. (Expedia.com)
• For group stays, recurring travel, or conference requirements, engage a local DMC/corporate travel agent to negotiate a corporate package. (en.wikipedia.org)

If you want, I can:

• Search and list specific Colombo hotels’ corporate package pages and their contact emails/phone numbers, or
• Find current package deals for specific dates and number of travelers (I’ll need your travel dates and party size).
