did you watch tv's Watchdog last night {Wed] about the Dominican Republic, they, Watchdog have a web site too.
I would seriously think about changing your destination especially if you booked with Airtours, last night they proved that even though AirTours passengers en masse were so sick on their return journey yhat the UK health authorites seroiusly wanted to quarantine all the passengers on arrival, good old Airtours still sent the next plane load of Brits to the same hotel. I dont think it was where you are going but double check everything.
