More than 50 venues and suppliers are exhibiting, including the National Railway Museum, Cedar Court Grand Hotel & Spa, and the Scarborough Spa, which is set to open its renovated facilities in spring.
York and Scarborough Conferences business tourism marketing manager Laura Freer said: "With the arrival of York’s new Barbican Centre and the Spa at Scarborough we have a stronger conference offer than ever before."
The showcase will be followed by a two course networking lunch at York Racecourse and buyers can also take part in afternoon site visits including tours of York venues.
The showcase will then move to Scarborough for an evening drinks reception and dinner, followed by site visits in the town tomorrow morning.
Sheriff of York, Councillor Richard Watson, will be adding his support to the event as well as meeting with the buyers in attendance. The Lord Mayor, Councillor Sue Galloway, will also welcome guests at Mansion House.
"By inviting conference organisers from across the UK to see firsthand what York and Scarborough has to offer, we aim to boost business tourism bookings for 2011 and beyond and we’re looking forward to welcoming buyers to the region," added Freer.
