Spirit of Adventure set sail on 22 February; a spokesperson confirmed to TTG the decision to turn round owed to strict Covid rules in the Caribbean.
The line declined to comment on the number of cases onboard the ship, but said a "limited number" of guests had contracted the virus and were either asymptomatic or showing only "very mild" symptoms.
“Sadly, we have been unable to continue with our current cruise to the Caribbean," said the spokesperson. "The strict entry requirements in the Caribbean meant we took the difficult decision to return to the UK. All guests are being given a full refund.
