CHECKING IN

Amazing Hotels: Life Beyond The Lobby, 8.30pm, RTÉ2

ION Adventure Hotel in Iceland, a sleek design-focused hotel levitating out from a dormant volcano, would be as at home serving as a supervillain’s secret lair as it is at welcoming guests. Those who visit do so expecting the adventure of a lifetime, a holiday spent exploring lava flows and glaciers, and snorkelling between the earth’s tectonic plates in icy water. Kicking off a new series, presenters Giles Coren and Monica Galetti learn what it takes to keep visitors safe on such hairraising excursions.
