The ship arrived in Dover late last month and will be officially named on Friday (5 July) ahead of its maiden voyage.
Spirit of Discovery and sister ship Spirit of Adventure, due in 2020, were designed specifically for the UK market.
TTG senior reporter Tom Parry was one of the first to board Discovery on Tuesday (2 July) – join him for a video tour (above) of the new ship, and hear the first thoughts of a handful of agents too.
Tom will also host a special Facebook Live broadcast from the ship on Wednesday at 10.30am with Saga chief operating officer Nigel Blanks and head of trade sales Iain Powell.
You can watch the broadcast live here at 10.30am or catch up after.
