This follows a spike in coronavirus infections in Spain, raising fears of a second wave.
In an effort to curb the spread of infection here, the new measures are forcing vacationers to stay at home, with strict measures indicating when they can leave, reports The Mirror.
The shock announcement dropped just three hours before it went into effect, a blow to thousands of vacationers.
Now Martin has warned travelers planning to travel to Spain to be extra careful.
Insurance policies may not cover vacationers
Most travel insurance will not be valid because the Ministry of Foreign Affairs advises against all but essential travel to mainland Spain.
Martin warns: “Think carefully before going to Spain.
“Although I know that some people argue, and rightly so, that some parts of Spain are badly affected and others that are not.
“Well, the Foreign and Commonwealth Office advises against all but essential travel to mainland Spain.
“You wouldn’t have travel insurance coverage, it’s not worth it.
“You stumble, you bang your head, you need treatment, you’re in the hospital, you need to fly back, it’s not worth it, things are happening. “
What if you don’t want to go?
Martin also issued advice for people whose theft is about to take place – but they don’t want to go.
Airlines easyJet and British Airways have both confirmed that their schedules are unchanged.
But TUI canceled all flights today, following its promise not to take vacationers to countries where they need to self-isolate.
But if your flight does go, it will be difficult to receive a refund, Martin warned.
He said, “I’m afraid you don’t have any rights.
“What you are also looking for is your travel insurance company.
“Now this is where it gets tough, you will be covered if you have booked your travel insurance and flight before the pandemic, you will likely be covered.
“So you can go talk to them, not to all of them but to most.” ”
But he cautions that if your vacation or travel insurance was booked after the Foreign Office changed its mind in mid-March, you’re unlikely to be covered.
He said: “Not all of the policies we have verified will cover you, the only one that can cover you is if you have a Nationwide Flex Plus package account that you pay for each month. ”
Brits booked to travel to the Canary Islands or the Balearic Islands may also be in trouble if they don’t want to go.
Martin said: “It should be remembered that you are allowed to travel to the Canary Islands and Ibiza.
“The Foreign Office says you can go, but you just have to quarantine yourself when you get home.
“Again, it’s even worse in some ways if you don’t want to go because even old travel insurance policies won’t cover you because it’s a reluctance to travel.
“Their problem isn’t that you have to quarantine yourself on the way home. “
Try to be flexible
Martin warned that many vacationers who travel to Spain could lose money.
He said: “I remember in March saying at the time that there will be significant circumstances where people will lose money on travel.
“And those people who have recently booked a vacation to go to Spain, even if you have travel insurance, you won’t be covered in most cases if the flight and hotel are still on.
“They would say it’s your problem. I would try to take every opportunity to move your flight for free.
“Because a refund is unlikely. I would also take advantage of any ATOL credit scores which are now backed by the government.
“I would talk to the hotel about trying to move your reservation to the future as you will have a hard time getting a refund.
“Sure, ask them for one, but if you get ‘no’ coverage, don’t expect your travel insurance to cover you. ”
The new quarantine measures, which began at midnight for all those returning from mainland Spain, also apply to those returning from the Canary Islands and the Balearic Islands.
A UK government spokesperson said: “The Joint Biosecurity Center and Public Health England have updated their coronavirus assessments from Spain based on the latest data. ”
“As a result, Spain has been removed from the lists of countries whose passengers arriving in England, Scotland, Wales and Northern Ireland are exempt from the need to self-isolate.
“Our list of quarantine exemptions and FCO’s travel advice is updated to reflect these latest risk assessments. “
