Great — below are top destination-wedding hotels and resorts across Sri Lanka (by region), a short note on what each offers for weddings, plus quick legal/planning pointers and next steps. I’ve listed the resort’s wedding page or official listing so you can contact their wedding team directly.

• Shangri‑La Colombo / Cinnamon Grand Colombo — large deluxe hotels in Colombo with full wedding services and ballroom/lawn options (suitable for very large guest lists and multi‑event city programmes). (shangrilaindiaweddings.com)

Quick legal & practical notes

• Many hotels offer full “symbolic” ceremonies and full wedding‑day production. If you want the marriage legally registered in Sri Lanka you’ll need to follow the country’s registration rules (hotels often help with the paperwork), or register at a Sri Lankan Embassy/Consulate — requirements differ if one partner is Sri Lankan vs both foreign. Embassy/Registrar pages outline notice periods, bachelor/unmarried certificates, possible security‑clearance requirements and witness rules. It’s common for couples to have a legal civil registration (at an Embassy or Registrar) plus a symbolic hotel ceremony. Confirm requirements with the Sri Lankan Registrar/Embassy and with your hotel coordinator. (un.int)
• Timeline: popular resorts fill fast — wedding/venue bookings for destination weddings are often made 12–18 months ahead, save‑the‑dates ~8–12 months out for international guests, and confirm key vendors (photographer, planner) 9–12+ months before the date. Plan a visit (if possible) or a virtual tour and lock the venue early. (destinationido.com)

How to pick and next steps (practical)

1. Decide region and guest count (beach vs hill vs city) — this narrows venue style and travel logistics.
2. Shortlist 2–3 hotels and contact their weddings/events team (ask about: sample packages, maximum guest capacity, buyout options, inclusions/exclusions, preferred vendor lists, and whether they can assist with legal registration). I included official wedding pages above for each property. (resplendentceylon.com)
3. If you’re bringing external vendors (florist, DJ, photographer) verify hotel policies and who covers travel/permits.
4. Book flights and a room block for guests as soon as you confirm a date; send save‑the‑dates ~8–12 months before the wedding. (business.lovu.travel)

If you’d like, I can:

• Narrow this to venues that fit a specific guest count, budget (per‑night or per‑person), or date range; or
• Draft an initial email you can send to several wedding teams asking the right questions; or
• Check availability/contact details for 2–3 properties you name and request their wedding brochures.
