Tickets for Dinner on Sea will close in 12th June

5th June 2023 at 12:38

As on previous years we will be holding a conference dinner in the evening during the conference week. This year that dinner will be ibn Thursday 29th June. Speakers will be our guests of honour and we usually have a high ratio of speakers to other guests - so this is a great chance to catch up with speakers in a relaxed environment. All this with views across the sea as the sun sets - and the food is great, too!

To prepare for this the venue's catering department needs to plan and order a couple of weeks in advance - so we will need to finalise our dinner guest list by the 12th June - that's just one week away as this post is published!

So if you haven't booked your ticket for Dinner on Sea already then please do so straight away to avoid disappointment.

Please note that we will follow-up your booking with an email to collect your choices for each course - so please make sure you are able to monitor the email address you register with.

C++ on Sea is hosted at the Leas Cliff Hall in Folkestone in Kent, UK, overlooking the English Channel. This historic seaside town is also home to the channel tunnel and, as such, has excellent links to the rest of europe. It's also very accessible from London with the UK's (currently) only high speed link, the HS1. For more comprehensive travel information, see the page, Getting to C++ on Sea

The Leas Cliff Hall is a working theater that also has a dedicated conference suite. Built into the cliffs, and with floor-to-ceiling glass overlooking the sea on three sides, the views are spectacular!

The venue is about a 15 minute walk from Folkestone Central station, or ten minutes walk to the bustling town centre. As well as the modern town the old quarter, home to art galleries, curio shops and bohemian cafes and restaurants, extends down to the picturesque harbour.

Although the venue is split across three floors, connected via staircases, it is also fully accessible via elevator.
