At a unique hotel in north Wales, Alex Jones and her team give people a once-in-a-lifetime chance to be reunited with someone pivotal from their past. 'Reunion Hotel' sees a young woman meeting the stranger who saved her life, secret siblings located and reunited, and a 60s girl band reconnecting with their favourite stars half a century later. Some check in to the Reunion Hotel seeking forgiveness, while others wish to say thank you or seek the answers they've long needed to know.
