Thistle London Marble Arch

The Marble Arch Hotel by Thistle occupies one of the most practical positions in central London for large-scale corporate events — Marble Arch tube is a two-minute walk, Oxford Street runs past the front door, and Hyde Park sits directly opposite. With 692 bedrooms and 13 meeting spaces on a single floor, it handles residential conferences, multi-day programmes, and large exhibitions without requiring delegates to leave the building.

Conferences at The Marble Arch Hotel

The Hyde Park Suite anchors the events offering — up to 500 standing or 400 theatre-style, with a partition wall that splits the room into two equal sections, each with its own entrance. That flexibility means a morning plenary can become afternoon breakouts without moving delegates between floors. An adjoining dining area keeps catering contained and separate from the conference space. Beyond the Hyde Park Suite, the Park Lane Ballroom brings its own built-in stage, high ceilings, and space for 280 theatre or 210 seated for weddings and awards dinners. Smaller rooms — the Albert Hall, Serpentine, Westminster, and Green Park suites — fill out a range from 4-person executive meetings to 50-person training sessions, all equipped with built-in screens, air conditioning, and unlimited Wi-Fi.

The Speakers' Corner Boardroom

Named for its views over Hyde Park and the famous Speakers' Corner, this is one of the more distinctive boardrooms in the West End. A mahogany table seats 25 beneath a chandelier, with a working fireplace and traditional British furnishings. It suits board meetings, client entertaining, and private dinners where the setting carries weight — the kind of room that justifies choosing a hotel venue over a dedicated conference centre.

What The Marble Arch Hotel Delivers for Events

In-house catering runs across all 13 spaces, with bespoke menus tailored by the hotel's chef team. Day delegate packages simplify budgeting for corporate organisers, while the events team coordinates everything from AV setup to overnight accommodation blocks. For conferences that need serious capacity, on-site bedrooms, and a W1 address that international delegates recognise, this is one of the few London hotels that scales from a four-person meeting to a 500-person reception within a single building.
