As the UK's coronavirus rates slow and the country takes its first tentative steps out of lockdown, many Britons are turning their sights to holidays abroad.
Currently, no one in the UK can travel overseas for non-essential reasons.
Those who do must quarantine at home (with two tests, on days two and eight, costing £210) or stay at a government-approved hotel (costing £1,750) if returning from a red-list country.
Ministers are considering vaccine passports for UK citizens, and further details on how travel could work are expected from the government's Global Travel Taskforce on 12 April.
EU chiefs are also expected to announce details of a vaccine "pass" that works in and outside Europe on 17 March.
But the decision to ease restrictions largely depends on the vaccine rollout, the effectiveness of the vaccine and the prevalence of coronavirus virus and its variants.
Nevertheless, several popular destinations have indicated they could welcome Britons in the coming months.
Here's what they have said.
Spain's tourism minister has said the country could begin utilising vaccine passports in May.
Maria Reyes Maroto confirmed the nation was pursing the idea and said she was "optimistic about the relaunch of international travel".
Spain has also said it will consider a "green corridor" for vaccinated British tourists if there is no EU agreement on vaccination passports.
However, in January it was widely reported Spain wouldn't welcome tourists until the end of summer.
Prime Minister Pedro Sanchez reportedly said Spain would "progressively" prepare to welcome international tourists once 70% of the population had been vaccinated, which he expected to be by the end of this summer.
The Balearic Islands
The Balearic Islands, which include popular holiday destinations Majorca and Ibiza, have already announced they want to be first to welcome foreign tourists with vaccine passports.
The Balearic Islands' minister for tourism, Iago Negueruela, told the Telegraph: "The Balearic Islands has proposed to Spain's central government that the archipelago becomes one of the first places where the vaccine passport is trialled."
The islands were part of a pilot scheme last summer which saw a travel corridor opened with Germany to welcome thousands of tourists, a week before Spain officially re-opened its borders to foreigners.
France and Germany
France is another country looking into a COVID-19 vaccine passport scheme, government spokesman Gabriel Attal said on Wednesday.
At the start of March, German health minister Jens Spahn said he wanted to see vaccination passports ready in 12 weeks, while Angela Merkel said technical work on vaccine passports should be completed by the summer.
Greece is one of the most popular summer destinations for UK holidaymakers - with Britons typically making more than three million visits to the country each year, according to the Foreign, Commonwealth and Development Office.
So, many people will be pleased to know the country is planning to reopen its borders by mid-May, paving the way for Britons when the UK allows international travel.
Tourism minister Haris Theoharis said the country hopes to welcome foreign tourists from 14 May, depending on the status of the coronavirus pandemic.
Visitors will be required to have been vaccinated, had a recent negative COVID-19 test or have coronavirus antibodies.
A "pilot" reopening of borders is likely to take place early next month, Mr Theoharis said.
Tourists islands with populations of less than 1,000 have already been made a "priority" for vaccinations.
These include Halki near Rhodes, Kastellorizo off the Turkish coast, Meganisi in the Ionian Sea and Kythira in the Peloponnese peninsula.
Mr Theoharis added: "Regarding 2021, in Greece we are more than optimistic.
"We are ready, we are ready to share the experience of liberation from the unpleasant memories of the pandemic with each and every one of our guests."
Cyprus will let British tourists who have had both COVID vaccination doses into the country without restrictions from 1 May.
This means visitors who have had both jabs will not need to supply a negative coronavirus test or quarantine, according to plans unveiled by Cypriot deputy tourism minister Savvas Perdios.
However, the UK government has said the earliest date people from England can travel abroad for a holiday is 17 May - provided the four tests for easing lockdown are met.
Visitors to Cyprus will need to have been given vaccines approved by the European Medicines Agency and the second dose must have been administered at least seven days before travel.
Authorities still have the right to carry out random tests on foreign arrivals, the tourism minister said.
"We have informed the British government that from 1 May we will facilitate the arrival of British nationals who have been vaccinated... so they can visit Cyprus without a negative test or needing to quarantine," Mr Perdios told Cyprus News Agency.
Portugal has said those who test negative for coronavirus, or were "immune", can visit from mid-May.
Rita Marques, Portugal's secretary of state for tourism, told the BBC: "I do believe that Portugal will soon allow restriction-free travel, not only for vaccinated people, but those who are immune or who test negative. We hope to welcome British tourists from 17 May."
It is unclear how Britons will prove they have been vaccinated or are COVID free.
Estonia, Poland and Romania
From 1 February Britons who have received a vaccination will no longer be required to isolate for 10 days or undergo testing in Estonia, the country's Ministry of Foreign Affairs said in January.
To qualify, travellers must have either recovered from COVID-19 no more than six months prior or had a vaccine no more than six months before hand.
Poland and Romania have also waived the self-isolation period for vaccinated Britons, although with some caveats.
Iceland is only allowing travellers with vaccine certificates that meet certain criteria including being issued in an EEA/EFTA state, to bypass testing and quarantine.
However, as the UK has left the EU we won't qualify unless any vaccine passports issued by the UK government are validated by the World Health Organization (WHO).
A spokesperson for the Ministry of Foreign Affairs of Iceland told the Mirror that "as soon as the UK vaccine certificates are validated by the WHO, we will be looking at whether we can accept them at our borders".
