Here are hotels in Sri Lanka that are typically used for VVIP / diplomatic stays (and able to support high security / private arrangements), plus practical next steps you should follow to arrange protection and logistics.

Top recommended (Colombo — proximity to government offices, embassies, airport)

• Shangri‑La, Colombo — large 5★ urban property on Galle Road with extensive ballrooms, executive/Horizon club facilities and a history of hosting government events and visiting delegations. Good for large official entourages and closed‑property events. (shangri-la.com)
• Taj Samudra, Colombo — long‑standing five‑star facing Galle Face Green; historic choice for visiting dignitaries with presidential / diplomatic event experience. (en.wikipedia.org)
• Cinnamon Grand Colombo — major five‑star with presidential/executive suites and large banqueting/meeting space; has been used for CHOGM/delegation accommodation in the past. (cinnamonhotels.com)
• Cinnamon Lakeside Colombo — large city hotel used for heads of state and summit delegations (CHOGM), with event/secure‑zone capability. (en.wikipedia.org)
• The Kingsbury Colombo — centrally located five‑star with VIP check‑in and 24/7 security features; commonly used for official functions. (thekingsburyhotel.com)
• Galadari Hotel / (soon Radisson Blu Galadari) — large central hotel with dedicated diplomatic/presidential suites and a history of hosting elite visitors. (galadarihotel.lk)
• Galle Face Hotel (heritage) — iconic seafront hotel used historically by heads of state and suitable for discreet, high‑profile stays when preservation/heritage profile is acceptable. (gallefacehotel.com)

Other secure / private options (non‑Colombo, for quieter or discreet stays)

• Amangalla (Galle Fort) — small, high‑privacy heritage property inside Galle Fort; useful for small VVIP delegations needing a secluded environment. (en.wikipedia.org)

Practical steps & coordination (required)

1. Notify and coordinate with Sri Lanka’s Protocol Division (Ministry of Foreign Affairs) early — they are the official focal point for arrivals/departures, airport VVIP handling, and state‑level protection coordination. Bookings for VVIP status, VVIP lounges and official meet‑and‑greet are routed through Protocol. (Contact info and guidance are published by MFA’s Protocol Division.) (mfa.gov.lk)
2. Ask the hotel for a written VVIP/VIP plan before confirmation: dedicated / lockable floors or wings, private entrances, ingress/egress routes, secured parking, screened access to restaurants/meeting rooms, private check‑in, secure internal lift use, CCTV coverage, and on‑site security liaison. Use hotels’ diplomatic/presidential suite pages or VIP sales teams to obtain those commitments. (Many Colombo hotels have formal VIP/presidential suites and VIP check‑in services.) (shangri-la.com)
3. Request official security support through the Protocol Division and Sri Lanka Police / Ministerial Security Division (MSD) as appropriate — during major summits Sri Lanka assigns MSD/police support to hotel VVIPs; you should confirm current MSD practices and availability for the dates of the visit.

4. Airport handling: reserve the Bandaranaike (CMB) VVIP/VIP lounge and fast‑track / meet‑and‑greet services via Protocol and Airport & Aviation Services — this is routine for visiting heads of state/dignitaries. Private meet‑and‑greet / fast‑track operators also operate at CMB. (mfa.gov.lk)
5. Send an advance/security team: hotel and state protocol will expect an advance party to do route reconnaissance, communications checks, medical evacuation planning, and to co‑ordinate with the hotel’s security manager and local police. Confirm communications, power backup and secure comms on site. (This is standard practice used during CHOGM and other state visits.) (archives.sundayobserver.lk)

Important caveats and recommendations

• Security arrangements and government procedures can change quickly (MSD/police allocations and VIP protocols have been adjusted in recent years), so you must confirm protection details with the MFA Protocol Division and the hotel for the exact travel dates. (hirunews.lk)
• For close‑protection / executive protection, use accredited security providers who are licenced to operate in Sri Lanka and coordinate them with the embassy/consulate and Protocol Division. Uncoordinated armed protection can cause legal/operational conflicts. (Protocol Division guidance is the authoritative route for official visits.) (mfa.gov.lk)

• produce a prioritized shortlist (e.g., top three by security capability vs. privacy) and draft a
